How did gold get on earth?
All of the gold found on Earth came from the debris of dead stars. As the Earth formed, heavy elements such as iron and gold sank toward the planet’s core. If no other event had occurred, there would be no gold in the Earth’s crust. But, around 4 billion years ago, Earth was bombarded by asteroid impacts.
Can gold be made?
Yes, gold can be created from other elements. But the process requires nuclear reactions, and is so expensive that you currently cannot make money by selling the gold that you create from other elements. Every atom containing 79 protons is a gold atom, and all gold atoms behave the same chemically.
Where is gold found in nature?
Gold is primarily found as the pure, native metal. Sylvanite and calaverite are gold-bearing minerals. Gold is usually found embedded in quartz veins, or placer stream gravel. It is mined in South Africa, the USA (Nevada, Alaska), Russia, Australia and Canada.

Why sodium is a soft metal?
sodium (Na): Sodium element is present in group 1 due to presence of one valence electron. It has a large atomic size, because of all these reasons sodium metal is a soft metal. Moreover, the metallic bonding in sodium is not strong, hence it can be easily cut.
How do humans use sodium?
Function. The body uses sodium to control blood pressure and blood volume. Your body also needs sodium for your muscles and nerves to work properly.
Is silver rare or common?

The abundance of gold in the Earth’s crust is estimated to be about 0.005 parts per million. That makes it one of the ten rarest elements in the Earth’s crust. Gold is thought to be much more common in the oceans. Some people believe as much as 70 million tons of gold are dissolved in seawater.
Is there gold on the moon?
Golden Opportunity on the Moon The moon isn’t so barren after all. A 2009 NASA mission—in which a rocket slammed into the moon and a second spacecraft studied the blast—revealed that the lunar surface contains an array of compounds, including gold, silver, and mercury, according to PBS.
Is there gold on the sun?
Eventually, scientists calculated that the Sun contains almost 2.5 trillion tons of gold, enough to fill Earth’s oceans and more. Still, that’s just eight atoms of gold for every trillion atoms of hydrogen — a tiny amount when compared to the mass of the Sun.
How much gold is left in the world?
Experts have estimated that we have less than 55,000 tons of gold left to discover. Even so, we cannot be sure how much of this amount is extractable. We know that the earth’s crust is gold in a proportion of about four parts per billion.
