A molecule is formed when atoms join together by chemical bonds. There are over a hundred different types of atom, called elements. The atoms of a particular element are identical to each other.
The atoms in a molecule are held together because they share or exchange electrons. Molecules are made from atoms of one or more elements. Some molecules are made of only one type of atom. For instance, two oxygen atoms bond together to form O 2, the part of the air that we need to breath to survive.
