Answer 1

Answer:

Answer

Correct option is

A

Na >Al

Sodium and Aluminium belongs to the same period.So,atomic radius decreases from left to right within a period. This is caused by the increase in the number of protons and electrons across a period. One proton has a greater effect than one electron; thus, electrons are pulled towards the nucleus, resulting in a smaller radius.

Hence radius of Na>Al and option A is correct answer.
