Pure sodium

\left( {Na} \right)

is a good conductor of electricity because the

3s

and

3p

atomic bands overlap to form a partially filled conduction band. By contrast the ionic sodium chloride

\left( {NaCl} \right)

crystal is

View answer and explanation

Correct option: A

Insulator

Option A (Insulator) is correct because in sodium chloride, the ions have noble gas configurations with completely filled bands and a gap between filled and empty bands.
