Types of Chemical Bonds

There are many types of chemical bonds. However, the three main types are ionic bonds, covalent bonds and metallic bonds.

• Ionic Bond:

An ionic bond is an electrostatic interaction between atoms that have a huge electronegative difference. An ionic bond is formed when an atom accepts or donates one or more valence electrons to another atom. A negative ion (Anion) and a positive ion (Cation) is formed during the chemical ionic bonding.

• Covalent Bond:

When a sharing of valence electrons happens between atoms, a covalent bond is formed. A polar covalent bond is formed when two atoms do not share the valence electrons equally.

• Metallic Bond:

A chemical metallic bond is formed when two metallic atoms share the valence electrons. A point noteworthy is, the valence electronics of any region of the metal atoms can be shared to form metallic bonds.
