← ScienceWhich outcome limits a solid NaCl crystal's electrical conductivity?
A)Limited mobile ion availability✓
B)Excess delocalized electron scattering
C)Dominant covalent bond interference
D)Strong van der Waals force damping
💡 Explanation
Ionic solids, because of their crystal lattice structure and strong electrostatics, rely on the movement of entire ions for charge transport. Therefore, a limiting factor exists when there are not enough mobile ions available, rather than electron scattering from metallic bonding.
