Question

atomic size of sodium atom is greater than that of chlorine atom... give reason...​

Answer 1

Answer:

By contrast, sodium not only has a lower positive charge, but it only has one lone electron in the outermost shell. That lone electron is dying to leave, so it gets to s... Chlorine has more protons which increase the positive charge in the center.

hope it helps ☺️

Answer 2

Okay so Atomic Size of Na atom Is Greatee than Atomic mass of Cl atom.If we See the Atomic numbers of both elements then

Na-11(2,8,1)

Cl-17(2,8,7)

now The Atomic size of Chlorine will be more as it has Large Nuclear charge as compared to Na.

Na has a positive charge of 11 while chlorine has a positive charge of 17 so the interionic force will be greater for chlorine and it will be shorter in radius
