The force of attraction between the opposite charges of the ions in an ionic compound
Contact [7]

The force of attraction between the opposite charges of the ions in an ionic compound is an ionic bond.

<u>Explanation:</u>

The transfer process of valence electron between atoms referred as ionic bond. This is a kind of chemical bonds which can create two oppositely charged ions. In the presence of ionic bonds, the metal loses electrons and becomes a positive charge cation, while non-metal accepts these electrons and becomes a negative charge anion.

Here, more than 1 electron can be emitted or received to meet the octet principle and the net charge of the compound should be zero. For example: Table salt. In this compound, sodium loses the electron to become N a^{+}, while the chlorine loses the electron to become c l^{-}.
