An ionic bond is one in which electrons are gained/lost, ions are formed, and they attract, forming an ionic compound (e.g., HCl, H2SO4,Li2O) A covalent bond is one in which electrons are shared, and depending on the size of the atoms involved, could be polar (H2O) or nonpolar (N2).

Ionic bonds typically form between a metal and a nonmetal, resulting in the transfer of electrons. Covalent bonds form between nonmetals where electrons are shared between atoms. The difference in electronegativity between the atoms can also help determine whether a bond is ionic (large difference) or covalent (small difference).

An ionic bond is generally between a metal and nonmetal where electrons are taken from one of the elements and given to the other. Another way to tell is if the electonegativity above 2.0

For covalent bonds they are generally between nonmetals ,and share the electrons. Also if the electronegativity difference is 2.0 or lower it is covalent.

A metal and a non-metal bonded together create an ionic bond.

Two non-metals bonded together create a covalent bond.
