Rule for radius
It decreases on going to right from left and it increases from top to down.
As>P
Cl- > Cl as negative charge repiulsion increases size.
Na> Mg
Cr> Cr3+ as +ve charge decreases size.
Se2- > Br- both are isoelectronic but -ve charge density higher for Se
Isoelectronic pairs means same no. of electrons Se2- and Br-
