An element is a substance that cannot be broken down into other substances and is made of only one type of atom. Copper is made of copper atoms only, carbon is made of carbon atoms only, and helium is made of helium atoms only.
There are about 100 naturally occurring elements, with a few more synthesized by scientists. Each element has its own distinct atoms and its own position in the Periodic Table.
Elements are represented using standardized Chemical Symbols, which make it easier to write formulas and discuss substances precisely.
