![]() ![]() When calculating the atomic mass of a particular element, we add up the mass of the protons and neutrons, because the mass of the electrons is negligible compared to their mass. The atomic mass of an element refers to the mass of one atom of that element, which is measured in atomic mass units (u), where one atomic mass unit is equivalent to 1/12 the mass of carbon-12 isotope. Gold can have a valency between (-1) and +5, the most common being +1 and +3. In a simpler form, the electrons per shell of the Gold atom can be written as 2,8,18,32,18,1. The electronic configuration of Gold is Xe 4f 14 5d 10 6s 1. The number of electrons present in each of the shells is known as the electronic configuration of an element. The atomic number of the element Gold is 79.Īn atom has various shells on which electrons revolve around the nucleus. An element is identified by the number of protons, which is given by the atomic number. The atomic number basically determines the number of protons in the particular element. This symbol is taken from the first two letters of the Latin name of gold: Aurum. First, the hydrothermal veins, where gold is associated with quartz and pyrite (fool's gold) and second, the deposits, which are mainly derived from the weathering of gold-bearing rocks Two types of deposits contain a substantial amount of gold. It is highly unusual to see large masses of gold-bearing rock rich enough to be called ores. Gold also appears in association with deposits of copper and lead, and while the quantity present is sometimes exceedingly small, it is readily extracted as a by-product in the processing of these base metals. The only isotope that occurs naturally for this element is Au-197. It is usually chemically pure, except with tellurium, selenium, and bismuth. It is estimated that its abundance in Earth's crust is about 0.005 part per million. It is widespread in all igneous rocks, at low concentrations. The IUPAC defines a transition metal as an element that has a partly filled subshell, or an atom that may give rise to cations despite having an incomplete subshell. Gold falls under the sixth period and group eleven in the periodic table. Gold is a precious metallic element with atomic number 79 and is a part of the periodic table. It is also soft and the most malleable and ductile of all the other elements and hence an ounce (28 grams) can be beaten out to 187 square feet (about 17 square meters) in extremely thin sheets called gold leaf. It is a good conductor of heat and electricity. Gold is one of the densest metals found of all other elements. Gold is a chemical element with the symbol Au derived basically from the Latin term aurum and atomic number 79, making it one of the higher atomic number elements that occur naturally. ![]() When gold is obtained in its pure form, it is seen as a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal. ![]() Our body is also made up of many unique chemical compounds, which are combinations of various elements.

![]() To find these formulas, we will use the explicit rule. The formula can be used to find any term we with to find, which makes it a valuable formula. The d-value is 4 because it is the common difference. Our n-value is 724 because that is the term number we want to find. So, if we want to find the 724th term, we can use this explicit rule. What if we have to find the 724th term? This method would force us to find all the 723 terms that come before it before we could find it. 23 + 4 = 27 so, 27 is the 7th number in the sequence, and so on. So, 23 is the 6th number in the sequence. To find the next number after 19 we have to add 4. ![]() We can see the common difference is 4 no matter which adjacent numbers we choose from the sequence. Let us say we were given this arithmetic sequence.įirst, we would identify the common difference. The recursive rule means to find any number in the sequence, we must add the common difference to the previous number in this list. To determine any number within an arithmetic sequence, there are two formulas that can be utilized. When we subtract any two adjacent numbers, the right number minus the left number should be the same for any two pairs of numbers in an arithmetic sequence. Remember, the letter d is used because this number is called the common difference. where n is any positive integer greater than 1. The d-value can be calculated by subtracting any two consecutive terms in an arithmetic sequence. This notation is necessary for calculating nth terms, or a n, of sequences. This means that if we refer to the fifth term of a certain sequence, we will label it a 5. Mathematicians also refer to generic sequences using the letter a along with subscripts that correspond to the term numbers as follows: Mathematicians use the letter d when referring to these difference for this type of sequence. So that we can examine these sequences to greater depth, we must know that the fixed numbers that bind each sequence together are called the common differences. The fourth number plus -2 is the fifth number: 14 + (-2) = 12.īecause these sequences behave according to this simple rule of addiing a constant number to one term to get to another, they are called arithmetic sequences. This too works for any pair of consecutive numbers. Sequence C is a little different because we need to add -2 to the first number to get the second number. The third number plus 5 is the fourth number: 36 + 5 = 41, which will work throughout the entire sequence. This also works for any pair of consecutive numbers. The second number plus 3 is the third number: 8 + 3 = 11, and so on.įor sequence B, if we add 5 to the first number we will get the second number. This works for any pair of consecutive numbers. įor sequence A, if we add 3 to the first number we will get the second number. The following sequences are arithmetic sequences: Sequence A: 5, 8, 11, 14, 17. Therefore, the least number of terms needed to make the sum negative is eight.Sequences of numbers that follow a pattern of adding a fixed number from one term to the next are called arithmetic sequences. ![]() We know that □ must be an integer or whole number value. In order for the sum of the arithmetic sequence to be negative, the number of terms □ must be greater than seven. ![]() Dividing both sides by five gives us □ is greater than seven. We can add five □ to both sides such that five □ is now greater than 35. In order for our inequality to be correct, negative five □ plus 35 must be less than zero. Since □ is the number of terms, this cannot be less than zero. When multiplying two numbers, if we want our answer to be negative or less than zero, one of the numbers must be negative. Multiplying both sides of this inequality by two gives us □ multiplied by negative five □ plus 35 must be less than zero. Simplifying the left-hand side of the inequality gives us □ over two multiplied by negative five □ plus 35 is less than zero. This gives us negative five □ plus five. ![]() By distributing the parentheses, we can multiply negative five by □ and negative five by negative one. Substituting these values into our formula, we have □ over two multiplied by two multiplied by 15 plus □ minus one multiplied by negative five. In this question, the first term of the sequence is 15. We recall that the sum of any arithmetic sequence, written □ sub □, is equal to □ over two multiplied by two □ plus □ minus one multiplied by □, where □ is the first term of the sequence and □ is the common difference. Find the least number of terms needed to make the sum of the arithmetic sequence 15, 10, five, and so on negative. ![]() ![]() ![]() Plant foreground and midground plants, including any epiphytes (a plant which grows by latching itself onto rocks or wood instead of soil). My attempt at a concrete explanation (step-by-step procedure): I can throw ideas, words and phrases out there, but nothing will come close to encapsulating the wonders of your very own underwater realm. Without Farkas and Green Aqua, The Aquascaping Type and countless other YouTubers and Insta-gram influencers, I would still not know how to truly define aquascaping. Five more months of constant research, content consumption and reading only brought me to spend hundreds of dollars to set up my own, admittedly amateur, tank. The “pursuit of making a better planted tank” didn’t end there however, as I soon found what I had truly been looking for, aquascaping. In September of last year, I ordered my first plants and tried my very best to make them look pretty in my small, scratched up plexiglass fish tank. ![]() For the two months that followed, I consumed every piece of content I could about planted tanks and keeping fish and plants together. In my search for methods to combat fatigue in my betta fish, I stumbled upon theidea of live plants in the aquarium. Over a year ago, I found the world of aquascaping and it blew my mind. If that definition feels overwhelming, I understand. The ‘scape’ will never be cemented in place-it is always in flux. Maintenance is not only key but what brings many joy. Aquascaping is not a transaction but rather a growing and forever changing work. From murky forests and rolling pastures to jutting spirals and graceful designs, the appearance is reflective of the creator.ģ. Once nature has been preserved, the mind is free to roam. The aquarium can also serve as a form of artistic expression. ![]() Where life is above all else, and where a home is built for the living organisms and ecosystem contained inside.Ģ. It is not a product of modern consumption, but the antithesis of it, an example of human control where responsibility, not power, is prioritized. The aquarium is not solely for the viewer. Most aquascapers would agree that there are three fundamental truths that define aquascaping in a deeper sense ġ. However, as evident in the complexity of the answers given by Alex and Ryan, there is more to the hobby than fancy fish tanks. Aquascaping is the artistic layout of substrate (such as sand or gravel), hardscape (stones and wood) and plants, where an ecosystem is created to fill the frame of the aquarium. ![]() ![]() ![]() del- / la quale ancora esistono gl'avanzi. che sono di travertino il tutto ricoperto dall'intonacatura di stucco.

Some historians argue that this is strong evidence for his involvement, but others have found it contradictory, as several aqueducts and even cities were proudly given his name. 1 According to the Historia Augusta, Hadrian also practiced the act of restoring the original inscriptions on his renovated monuments without leaving his own name, a testament to his modesty. After research proved that the monument was a reconstruction, a second debate regarding the benefactor’s identity ensued.Īccording to historical records, Hadrian was known as a strong patron of the arts, and especially invested in the reconstruction and refurbishment of several ancient monuments around Rome. Because of its clarity, the inscription confused early historians who lacked the technology to establish the monument’s true construction date. On the surface, the inscription on the Pantheon indicates that Marcus Agrippa had commissioned the current building. Marcus Agrippa, son of Lucius, consul three times, made Francesco Piranesi (Italian pronunciation: frantesko piranezi -esi 1758/59 23 January 1810) was an Italian engraver, etcher and architect.He was the son of the more famous Giovanni Battista Piranesi and continued his series of engravings representing monuments and ancient temples. ![]() ![]() ![]() ![]() They're the perfect accessory for your concert, festival, disco or dance party outfit.

It's still part of the fun, grappling with the controls, often with hilarious results. There's also some object crafting in the game, again following in DayZ's rotting footsteps, so you can get creative with what you use to attack the undead.ĭespite the invasion of zombies, which changes the atmosphere, the controls are just as silly and imprecise as ever. In this expansion the goat also needs to find food and not be killed, so you'll be searching for sustenance as well as attacking the infected. The controls are the same, and the goat has the same range of movements, like using its tongue to grab objects and people. If you've already played Goat Simulator, you'll have no trouble playing this expansion. Surviving a zombie outbreak is easy…if you know how You have to survive the zombie outbreak for as many days possible, without any other particular goals beyond doing crazy things, creating chaos, and just enjoying the absurdity of it all. Once you turn someone into a zombie, they'll try to attack you, so you have to immediately try to escape.Įxcept for the start of Before Outbreak, both modes end up being pretty similar. In After Outbreak, the world is already plagued by zombies, and the goat's objective is simply to survive. In Before Outbreak, our favorite goat wakes up with a clear objective: create chaos by infecting every living thing it meets, therefore causing the zombie outbreak. There are two game modes, Before and After Outbreak. As a sandbox game, you can freely roam wherever you like in its open-world, creating whatever madness you like. Goat Simulator GoatZ parodies this, happily laughing at both the game it mocks and itself. It's a reference to the popular DayZ zombie survival sandbox game, which itself started life as a mod for another game ( ARMA II). ![]() ![]() The only solution I found is to restart the app and go back online, but this is not a convenient solution when travelling without service.
