Question

state the reason why 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:

sodium being more electropositive is more metallic than aluminium.

Explanation:

electropositivity is a characteristic of metals..the more electropositive an element is , the more metallic it is considered.

as sodium is more electropositive than aluminium, it is more metallic than aluminium
