Why Na is larger than that of Li ?

Question

Why Na is larger than that of Li ?

Answer 1

The outer shell of lithium is the shell L where n=2, whereas that of Na is M where n=3. The larger n the greater is the distance electron nucleus and the size of atom

Answer 2

becoz no of shells in Na i.e 3 is more than no of shells in Li i.e 2 .

Answer 3

Your question isn't clear.  

Answer 4

well going down the groups size increases as positive charge is same but electrons increases thus radius increases .......

Answer 5

the s3 orbital in Na is further from the nucleus than the s2 orbital in Li... as well as this, the Na has p2-orbital electrons that shield the s3 electrons from the attractive forces of the protons.

As a result it is larger.

Generally, the closer you get the bottom of the periodic table the larger the atom (with a few exceptions).

Answer 6

Why not?

Answer 7

Na hss greater number of shells than that of Li . Hence it is larger than that of Li.
