← ScienceWhich outcome results when lithium iodide is extremely compressed?
A)Metallic conduction becomes thermodynamically favourable✓
B)Covalent character completely replaces ionic
C)Iodine molecules become completely unstable
D)Electronegativity difference becomes insignificantly measurable
💡 Explanation
Increased pressure forces increased electron delocalization; metallic behaviour then arises because the band gap closes giving rise to electronic conductivity rather than structural changes. Instead of promoting iodine instability or obliterating prior electronegativity.
