GOLD!
Discovery...
People aren't sure of who discovered the element gold because it has been around for about 5,500 years. They don't know how it was discovered because it could have been discovered in a stream and it was glowing. It could have been discovered when someone was building something and ran into it. If you put gold in water and then take it out and see the volume. The volume should be 19.3 g/cm3. Put it under the sun and it should obtain its color. You can find gold in almost every state and it may be in streams, canyons, or it may just be in the ground. It is commonly found as an element. There are no common compounds for gold. It is found in many things though.Gold is in period six and it group number is eleven. The reason it is in period six is because it has some magnetic properties and may have some toxic in it. The reason it is in group number eleven is because it has low electrical resistivity. It is also very hard to make fake gold.
There has been about 152,000 metric tons of gold dug out of the ground! One out of a billion atoms or rock are gold!
