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
Gold is recyclable material and it has a definite supply chain systems. In contrast, some sort of gold has particular features, including its natural value and handiness. And these have created it a possible source of investment for unlawful armed groups complex in civil wars and revolts. It is essential that the society take responsibility to reduce misapplication of gold. The uses of gold are enormous. Gold is not a decorative material anymore. Its usages are being more fundamental and essential to our contemporary generation. Consequently without using gold and culture of gold, people would be living in totally different way. Possibly, A lifetime is less technologically developed and unquestionably the world and cultures are less beautiful.
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.
-Discuss the silver vs. gold argument, listing at least one argument for silver and one argument for gold.
Within the Gilbane Gold case, the major problem is the contribution of water pollution by dumping chemicals to speed production for Z CORP. However, there is doubt as to what extent the company violated city regulations. Tom Richards believes that Z-CORP broke regulations repeatedly but Professor Massin believes that it is not solid evidence. Part of the problem is that two different tests are involved: an older and a less sensitive test which does not break regulations but there is also the newer and more sensitive one which does. The newer test was said that the company just broke city regulations, but not by a large amount.
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 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
The writings of some Greek philosophers may be considered to be among the very first chemical theories, such as the theory that all things are composed of air, earth, fire, and water. Each of these were represented by different elements, such as sulfur, salt, mercury, and, ideally, gold. Other ideas held by alchemists were that each of the known elements were represented by heavenly bodies. Gold was earth's representation of the sun, silver for the moon, mercury for the planet Mercury, copper for Venus, iron for Mars, tin for Jupiter, and lead for Saturn.
"The title of the poem is metaphorical and gold represents value and wealth so when it says nothing gold can stay it
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.
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.
