A covalent bond is a bond between 2 non-metals (sharing of electrons between atoms), where ionic is between a metal and a non-metal (the transfer of electrons). Standard covalent bonds are usually weaker then ionic bonds.
Covalent - Hydrogen + Chlorine = Hydrogen Chloride (HCl)
Ionic - Sodium + Chlorine = Sodium Chloride (NaCl)
