Ionic, covalent, and also metallic bonds space different species of chemistry bonds. An ionic bond is formed when one atom donates valence electron to one more atom. A covalent bond is created when both the atom share pairs of valence electrons. A metallic bond is formed in between a cloud of totally free electrons and the positive charges ions in a metal.

In ionic and also covalent bonds, the valence electrons play a an essential role in developing the bond. Atoms accomplish a stable digital configuration through transferring and sharing that electrons. Together a result, the bonds become stable v well-defined strength and energy.
