When two or more atoms chemically bond with each other, the resultant chemical structure is a molecule. The familiar water molecule, H2O, consists of two hydrogen atoms and one oxygen atom, which bond together to form water . Atoms can form molecules by donating, accepting, or sharing electrons to fill their outer shells. These processes go under Covalent or Ionic bonding. A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. It only happens between non-metal atoms. Ionic bonding involves the electrostatic attraction between oppositely charged ions, and is the primary interaction occurring in ionic compounds.Atoms turn into ions when they lose or gain electrons. Since the atoms are particles in the matter,
