The atomic radius of a chemical element is a measure of the size of its atoms, usually the distance from the nucleus to the boundary of the surrounding cloud of electrons.

Explaining periodic trends in atomic radius. See the section on factors affecting the valence shell above.
trend valence
n		 Z core
electrons		 net effect on atomic radius
going right across main group rows... no change increases no change the increase in Z causes a decrease in radius
going right across transition series... no change increases increases the increase in Z causes a decrease in radius, but the increase in the number of core electrons causes an increase. The two competing effects cause a small decrease, then small increase!
going down groups... increases increases increases three competing effects; but n is strongest, so radius increases.
