Answer the case-based question given below:
An ionic bond is the type of chemical bond in which two oppositely charged ions are held through electrostatic forces.
We know that, metal atoms have loosely bound valence electrons in their valence shell and non-metal atoms need electrons in their valence shell to attain noble gas configuration.
The metal atom loses the valence electrons while non-metal atom accepts these electrons.
By losing electrons, metal atoms change to cations and by accepting electrons, non-metals form anions. Ionic compounds are generally solid and exist in the form of crystal. They have high melting and boiling points.
