Answer 2

Answer:

The sodium $(Na)$  metal's electrical conductivity is less than that of aluminum $(Al)$ metal. The correct option is less.

Explanation:

• The atomic structure determines the electrical conductivity of the matter.
• If the number of free electrons is more, the matter has a high electrical conductivity.

In aluminum, the outermost shell has more electrons than the sodium atom (aluminum has three while sodium has one).

Hence, due to more electrons in the outermost shell, the electrons can move more freely in an aluminum atom.

So, the sodium $(Na)$  metal's electrical conductivity is less than that of aluminum $(Al)$ metal. The correct option is less.
