Gold By Amanda

What is Gold? Gold is an element that is also known as AU. In the dictionary, it is stated that gold is a precious yellow metallic element, highly malleable and ductile, and not subject to oxidation or corrosion. In other words, gold is a metal that has a yellow color. It is very easy to melt and form into many different types of jewelry. It is also wealth and a form of deposit for many families in the world. Gold is one of the most valuable metal in the world and if its price increase or decrease, it will affect a lot of people. It is one of the few elements that many people are familiar with.

Simple Facts About Gold Gold is also known as AU Its boiling point is 3080 Its melting point is 106 Its atomic number is 79 Its atomic weight is It is a metal

Where and When Gold is Discovered Many scientists aren’t sure of the exact time gold is found. All the know is that gold has been around on earth for a long time. Nobody really knows where and when it is found but gold is very famous for its beauty. On of the earliest gold discoveries was in Crete, Egypt and Sumer in the year 3000 B.C. People say that the Egyptians were the first ones to find it. Egyptians found golden nuggets at the sides of the Nile river. In a while, Sumerians, Minoans, Mycenaeans, Egyptians, Etruscans and others became skilled goldsmiths and made wonderful jewelry. In the old times, gold was embroided in the royal family’s clothing along with other precious rocks.

Hazardous Effects of Gold Gold can cause irritation and allergic reaction to our bodies, but this rarely happens and if it does, it can be cured. Gold mining is the one that produces a big issue. It is one of the main reasons for global warming and it isn’t environmental friendly. It produces bad pollution because of the machines being used and it can cause a lot of landslides. Because gold can only be found deep underground, people are trying every way they can to take it out of the earth. They have to drill the ground which is also bad because first of all, it ruins the habitat of many animals and second, it also causes pollution.

Uses of Gold Gold is used as fake teeth for the elderly because it is chemically not reactive. Gold teeth allows you to eat anything without getting poisoned or getting a bad disease. Gold is used as wedding rings because of its density. It can be used for many years and will not tarnish. It will keep its color even when it is washed. Gold is also used as a storage of wealth. People keep it in the bank, or deposits for the future. Even a gold necklace can be sold for a high price in the future and the money can be used for everyday life.

Types of Gold

14k Gold This type of gold is the gold that many people are familiar with. It is pure gold and isn’t mixed with any other type of element. It is usually in the shape of bars because it can’t be easily shaped into jewelry. It is usually stored in safe places or used as a storage of wealth.

24k Gold This type of gold is the one that we usually see. The type that can be easily melted and shaped into necklaces, rings, and others. It is very light and will dry very easily after being melted and formed.

Palladium White Gold This type of gold may often disappoint customers because of its color. It is supposed to be white but it’s color is originally a bit yellow. Because of this, shop owners often use rhodium to make the gold look more white.

Did You Know? Gold was a barter material in the form of coins in the early years and was first effectively used in Turkey. Gold was found laying around on river banks (Imagine that happening today. People can get rich just by collecting rocks beside rivers!) Eating gold dust can cause death. Two stories were posted about a man and a woman who died because of accidentally eating gold dust.
