I was solving gen chem problems about ionic and atomic radius.

i am keep getting wrong. Is there any tips how to solve problems?

Thanks

Fr has the largest atomic radius, its down and to the left of the periodic table. As a tread remember the atomic radius increases as you go down and to the left on the periodic table.

I have to brush up (pun intended lol) on the ionic radius myself though.

What kind of problems were you getting? Atomic radius increases from right to left, then from top to bottom of the columns. Ionic radius's depend on whether it is an anion (negative) or a cation (positive), so a anion will be smaller than a cation because less orbitals being filled by electrons (less shielding) and it would be the reverse for cations.
