How are ionic and covalent bonds similar

They are similar because they both have a similar need for electrons. An ionic bond is a bond between a metal and a nonmetal and a covalent bond is a bond between two nonmetals.

Ionic bonding occurs between atoms that have opposite needs for electrons (metals and nonmetals) and results in a transfer of electrons. Covalent bonding occurs between atoms that have similar needs for electrons (two nonmetals) and results in a sharing of electrons.
