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