Question

The electrostatic force of attraction between oppositely charged ions is known as ……………………………………….

Answer 1

Definition of Ionic bond

• The electrostatic force of attraction between oppositely charged ions is called Ionic bond.
• An ionic bond results from complete transference of one or more electrons from the valence shell of an atom to the valence shell of other atom.
• The atom which loses the electrons acquires a positive charge called cation. The atom which gains electrons acquires a charge called anion.

For example, Formation of NaCl.

$$\begin{gathered} {}_{11}Na-2,8,1 \\ {}_{17}Cl-2,8,7 \end{gathered}$$

$$\begin{gathered} Na\to N{a}^{+}+e^{-} \\ Cl+e^{-}\to C{l}^{-} \end{gathered}$$

$N{a}^{+}+C{l}^{-}\to NaCl$

The electrostatic force of attraction between two oppositely charged ions is called Ionic bond or electrovalent bond
