Atomic Radius vs Ionic Radius

Postby 205154661_Dis2J » Fri Dec 06, 2019 10:14 am

I know atomic radius and ionic radius both follow the same periodic trend but what is the difference between them?

The trend for ionic radius is the same for that of atomic radius, but the discrepancy is that when you go down a period towards nonmetals that form anions, the ionic radius jumps as anions are larger than cations, but then continues to follow the trend.

Atomic radius is half the difference between neighboring atoms, while ionic radius is one half the distance of two atoms joined by an ionic bond.

Also the radius of an anion will be bigger than its parent's atom because the added electron(s) will lead to more repulsion. The radius of a cation will have a smaller radius than it's parent atom because the remaining electrons will be pulled closer to the nucleus
