pls mark brainlest

Explanation:

(a) Since the bond formation involves loss and gain of electrons, the bond formed must be ionic.

(b) Formation of MgCl

(c) When NaCl is melted, the ions become mobile. Due to this they can conduct electricity.

(d) Due to strong electrostatic interactions between the ions Na  

+

 & Cl  

−

 , more energy is required to break this interaction. Hence, due to this it has high melting point.
