Answer 1

psssttt, you don't need to tag everyone else ;p

also, do you remember learning about atomic radii?

Answer 2

I would think its the atom's number and arrangement of electrons?

Answer 3

Bingo, the more electrons we have, the more orbitals we'll have and that makes the atomic radius bigger :)

Answer 4

Ok thanks!

Answer 5

Anytime! :)
