They are found throughout your body, mostly as water but also as components of biomolecules such as proteins, fats, DNA and carbohydrates.
Is silicon a metal?
Silicon is neither metal nor non-metal; it’s a metalloid, an element that falls somewhere between the two. The category of metalloid is something of a gray area, with no firm definition of what fits the bill, but metalloids generally have properties of both metals and non-metals.

What are the 7 elements of the world?
Classical elements typically refer to earth, water, air, fire, and (later) aether, which were proposed to explain the nature and complexity of all matter in terms of simpler substances.
What is the rarest metal?
franciumThe rarest stable metal is tantalum. The rarest metal on earth is actually francium, but because this unstable element has a half life of a mere 22 minutes, it has no practical use.
What is the rarest element in the universe?
AstatineAstatine is the rarest naturally occurring element.
Why is oxygen so common in the human body?
Oxygen. Oxygen is the most abundant element in the human body. … This is due mainly to the body’s water content. Water makes up the majority of the human body, and the two elements that make up water are oxygen and hydrogen.
Why is there gold in the human body?
