Question

Sodium is more metallic than aluminium.

✓

Answer

Metals give electrons. Sodium has electronic configuration (2, 8, 1). It has only one electron in the outermost shell.
It can easily give a single electron in the outermost shell. Hence, Sodium is a strong metal.
Aluminium has an electronic configuration (2,8,3). It has three electrons in the outermost shell.
Donation of three electrons is more difficult than the donation of one electron. Hence, sodium is more metallic than aluminium.
