What is the difference between an ionic and covalant bond?
A covalant bond is a very strong bond between two atoms. These atoms share a pair of electrons and form molecules.
An ionic bond occurs between two ions (charged atoms). Ions form when an atom loses or gains electron(s). An ionic bond occurs between oppositely charged ions.
