Which outcome results when high pressure is applied to sodium chloride?

A)Increased density, lattice volume decreases
B)Metallic bonding character increases
C)Covalent bond formation is favored
D)Sublimation due to increased vibrational energy

💡 Explanation

Metallic bonding character increases because the increase in electron delocalization induces a change in the electronic band overlap; therefore promoting metallization is the outcome, rather than increasing covalent character. This is because the distance allows electrons to move easier.
