Answers

Answered by mayursagare873

Answer:

Step-by-step explanation:

We can see that sodium and aluminium are in the same period (3) and electrons in aluminium are added in the same shell as that of sodium. Thus, the effective nuclear charge is more on aluminium than sodium and thus aluminium has a smaller size. ... This makes sodium more metallic than aluminium.
