Question

Solid $\mathrm{NaCl}$ is a bad conductor of electricity because:

• A. in solid $\mathrm{NaCl}$, there are no electrons
• B. in solid $\mathrm{NaCl}$, ions cannot move freely
• C. in solid-state, there are no ions
• D. none of the above

Answer 1

The correct option is B

in solid $\mathrm{NaCl}$, ions cannot move freely

Explanation:

Insulators: Insulators are those materials that will not allow electricity to pass through them easily.

• Even they are not used for the making of electric circuits.
• Basically, bad conductors or insulators are those materials in which the charged particles are not free or easy to move around here and there internally.
• In the solid $\mathrm{NaCl}$, the ions cannot move freely here and there as they are bound by strong electrostatic forces of attraction.

Therefore, the correct answer is (B).
