Question

which has the bigger atomic size, O or Cl and why?

Answer 1

Answer:

The size of chlorine decreases because there are more protons in its nucleus but the electrons are all in the same orbit so they are pulled closer to the nucleus so the size is smaller. The electrons in chlorine are held more closely and tightly together than that of lithium, so lithium has a larger atomic radius.
