← ScienceWhich 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.
