Ionic, covalent, and metallic bonds are different varieties of chemistry bonds. An ionic bond is developed when one atom donates valence electrons to another atom. A covalent bond is created when both the atoms share pairs of valence electrons. A metallic bond is formed between a cloud of totally free electrons and also the positively charges ions in a metal.

In ionic and also covalent bonds, the valence electron play a vital role in developing the bond. Atoms attain a stable digital configuration by transferring and sharing that electrons. As a result, the bonds come to be stable v well-defined strength and also energy.
