Question

Sodium is more metallic than aluminum

Answer 1

Answer:

Thus, removal of electrons from aluminium requires higher energy than sodium i.e. ionization energy of aluminium is higher than sodium. This makes sodium more metallic than aluminium. Also, upon losing one electron sodium will gain a stable nearest noble gas configuration thus it will lose electrons readily

Answer 2

Answer:

Removal of electron from aluminium requires higher energy than Na i.e ionisation energy of Aluminium is higher than Na. This make Na more metallic than Al.
