Question

When does an ionic bond is formed?

Answer 1

Ionic bond

• An ionic bond is a chemical bond involving electrostatic attraction between two atoms or ions with sharply differing charges.
• It is the electrostatic force of attraction that holds the two oppositely charged ions together.

Formation of ionic bond

• During the formation of an ionic bond, one atom loses one or more electrons and the other atom gains the electrons.
• The atom losing electron is called a cation and the atom gaining electron is called an anion.
• When the transfer of electrons occurs, an electrostatic attraction between the cation and anion takes place and an ionic bond is formed.

Hence, an ionic bond is formed by the complete transfer of some electrons from one atom to another.
