The Element Gold Discipline: Chemistry I am going to discuss about the element known as gold in my assignment. To describe the element gold in simple terms, I can only say that it is an element (chemical element). This element is denoted by the symbol Au. It has an atomic number of seventy nine (79). I will describe quite a number of things concerning gold as an element. To begin with is: Physical properties Gold contains several properties that are visible through the human eye. It is these properties that will greatly differentiate gold from other existing elements in the earth. These physical properties make gold unique. The element gold is yellow in color. It is actually a very bright yellow color. When it comes to its luster, gold is …show more content…
Gold is a metal that is dense. Its density can be felt. It is not negligible as some elements appear to be. The element gets melted from solid to a liquid when it reaches a temperature of up to 1066 degrees. This is the melting point of element gold (Saunders, 2003). Chemical properties of gold Gold bears quite a number of chemical properties that I will discuss in details down here. These point out on how gold behaves at various conditions. The chemical formula of gold is Au which is derived from its chemical name. When it comes to gold’s activity, it is not chemically active. This means that it greatly resists any kind of chemical reaction. In most cases, it rarely reacts with other chemicals. Gold is easily reduced from a compound to become a metal. It has two main compounds. These compounds are the Chloral-auric acid as well as the auric chloride. When we come to how gold reacts with certain acids, it is clear that there is an acid that is very able to dissolve this element. This acid is known as Aqua regia and is a combination of hydrochloric and nitric acids. Gold is not able to react with non-metals. Under this case, it only reacts with halogens and forms what is known as halides. The main alloys that can be used to make gold harder include platinum metal and silver (Tocci,
Three pieces of evidence from the text that shows the motivation behind the “gold fever” is that at the time many Americans were earning low wages or either had no work. This means that people with a job or that earned a little bit of money wanted to find gold to be kind of rich. Another piece of evidence that I found was that people were rushing to the grocers, hardware merchants, and the clothiers. This means that the people wanted to get ready to go find gold, so they went to different shops to go get stuff like materials like footwear, gold pans, buckets, and more items. The thing that gave the people a reason to travel to Alaska in search of fortune is that when
Yellow gold has taken a back seat in recent years to other colors of gold and platinum. However, yellow gold is huge on the couture scene no matter what the jewelry piece or style. It can still be mixed and matched with other precious metals and is always a classic look no matter what the piece or outfit. In larger pieces, gold's natural beauty and reflectivity give any outfit that extra sparkle it deserves. Check out this slide show for an example of yellow gold's versatility in bold styles.
Gold is one of the most valuable materials all around the world. This jewel has its own glittering appearance and shiny color which induce people to desire to possess it. That’s probably why Europeans in the middle age have explored new continents and invaded other civilizations to find this glittering material. Americans also had given much endeavor to mine that valuable jewel in the time of gold rush. Investigating these events, gold has immensely affected the world history; the Age of Exploration, invasions of Spaniards, and the development of California.
Aluminum is a lightweight, silvery metal. The atomic weight of aluminum is 26.9815; the element melts at 660° C (1220° F), boils at 2467° C (4473° F), and has a specific gravity of 2.7. Aluminum is a strongly electropositive metal and extremely reactive. In contact with air, aluminum rapidly becomes covered with a tough, transparent layer of aluminum oxide that resists further corrosive action. For this reason, materials made of aluminum do not tarnish or rust. The metal reduces many other metallic compounds to their base metals. For example, when thermite (a mixture of powdered iron oxide and aluminum) is heated, the aluminum rapidly removes the oxygen from the iron; the heat of the reaction is sufficient to melt the iron. This phenomenon is used in the thermite process for welding iron .
In chemistry, out of all the elements on the periodic table, there are a few that stand out because of certain characteristics, Gallium is one of these elements. On the periodic table, Gallium has the symbol Ga and atomic number 31. Gallium is a metal that has uses in such things as, medical, industrial, and everyday life.
-Discuss the silver vs. gold argument, listing at least one argument for silver and one argument for gold.
The gold standard was a commitment from participating countries to set their currencies in terms of specified amounts of gold. The country’s government allows its currency to be converted into a set amount of gold and vice verse. The main benefit of a gold standard is to help keep inflation low since it is caused by changes in the supply and demand of money and goods. The government cannot print too much money because the supply of money would increase, but the value of gold would remain the same and eventually would result in the treasury running out of gold. This is tricky because the government could not increase the amount of money in circulation without also increasing the country’s gold reserves. The extensive use of the gold standard implies a system of fixed exchange rates where gold is really the only
Potassium is a solid silvery white element. It is soft and can be cut with a knife. Potassium is the least dense known metal, besides lithium. It is the seventh most abundant element. It makes up about 1.5% by weight of the earth's crust. It decomposes in water because of the hydrogen. It usually catches fire during reaction with water.
The noble gases are group 18 of the periodic table and are chemical elements with similar properties. All of the noble gases have a full outer shell. None of them have color, odor, and all have very low chemical reactivity. There are six of them and they are Helium, neon, argon, krypton, xenon, and radon.
The usage of gold is not limited to banks and jewelry industry. This metal is also usable to a wide array of industries, such a medicine, electronics, dentistry, and aerospace.
Gold jewelry demand runs high in South Asia, East Asia and the Middle East. Women in the Sub-Continent would use gold as adornments and or store of value. Smart housewives prefer their savings in gold jewelry instead of holding it in cash form and it is passed onto, in gifted form, to daughters and sons at the time of wedding.
"The title of the poem is metaphorical and gold represents value and wealth so when it says nothing gold can stay it
Gold is the “noblest'; of the noble metals (gold, platinum, palladium, and rhodium), so termed because of their inertness, or reluctance to enter into chemical reactions. Gold will not react with common acids but is attacked by a three-to-one mixture of hydrochloric and nitric acids. This combination is called aqua regia because it reacts with the so-called royal metal. Gold will not combine directly with oxygen, but oxides may be formed indirectly. Gold will also combine with the halogens (fluorine, chlorine bromine, and iodine) and with the cyanides.
The Periodic Table of Elements is commonly used today when studying elements. This table’s history begins in ancient times when Greek scientists first started discovering different elements. Over the years, many different forms of the periodic table have been made which set the basis for the modern table we use today. This table includes over 100 elements and are arranged by groups and periods. Groups being vertical columns and periods being horizontal columns. With all of the research conducted over the years and the organization of this table, it is easy to use when needed.
