← ScienceWhich outcome limits conductivity in molten ionic salts?
A)Ion-cloud asymmetry reduces ion mobility✓
B)Charge screening increases free carrier lifetime
C)Quantum tunneling shorts available pathways
D)Magnetic confinement inhibits ion delocalization
💡 Explanation
Ion-cloud asymmetry reduces ion mobility because *ionic* atmosphere around each ion becomes non-spherical under an applied electric field, hindering its movement; therefore, conductivity decreases with asymmetry, rather than increased carrier lifetime because this relates to electron holes.
