Elements are composed of atoms, the smallest components that maintain the chemical properties of that element. Water is a compound, made of two hydrogen atoms bonded to one oxygen atom, Atoms can link chemically to form molecules combinations of two or more atoms. Molecules composed of two or more atoms from different elements are called compounds. denoted as h2o. Elements, molecules and compounds can come together and mix without chemically bonding or reacting, called a solution ex.
