Gold


Located in Group 11 and Period 6 of the Periodic Table is our favorite topic ( and things ) : a shiny, yellowish nice things that makes you rich! This is Gold.

There was one era in the States called Gold Rush, where many people flocked to California in search of Gold. It was indeed an exciting experience for the Americans. Americans either found gold or found nothing at all. Although many people claimed to have discovered Gold, the credit still goes to James W. Marshall.
Sutter Creek

James was actually overseeing a construction of a sawmill on the American River when he unexpectedly saw a shiny object in the Sutter Creek near Coloma, California. He notified his nation and eventually the place got famous. People from everywhere went to find gold. Some people got very rich and some people stayed the same.

Although Gold was to be believed to be existing at Ancient Egypt around 3000 B.C where was believed that human have interaction with gold at that time. Gold, at that time was to be made into Jewelries, Sarcophagus ( Ancient Egyptian Tomb ) and even for decoration. It was believed that gold had been existing for a very lon
Sarcophagus
g time.

Gold is usually alloyed with Silver, Copper, Platinum or Palladium, to, of course, increase its strength. And, of course, it would be very expensive.

Gold is the rarest element in the universe, which contains 0.004 parts per million, followed by Platinum, which is 0.005 parts per million, then Silver, which is 0.075 parts per million. ( Please do not get confused with Minecraft... we know you can find Gold anywhere in Minecraft but you cannot find much in real life... accept the reality... )
Golden Everything

Besides, Gold is also one of the ten rarest element of the earth crust, which is estimated to have 0.005 parts per million. However, Gold is to be believed that there might be a possibility that 70 million tons ( 63502931800 kg ) of Gold might be dissolved in the seawater.

We can actually find 0.2 milligrams of Gold in our body, which I do not recommend you killing people for Gold... but yes... there are actually traces of Gold in our body, perhaps even there are small traces of Gold found in Eucalyptus Trees.

How does Gold got its name?
Gold got its name from the Germanic Word Gulpha which means... gold. The old English Word Geolu means Yellow. Which after that both name forms together and eventually called Gold. In Latin, Gold was called Aurum, which means yellow, the color of Gold. The word also comes from a Sanskrit Word ' hari ', which also means yellow, the color of Gold.
