Hello Student,
Atomic radius decreases from left to right within aperiod. This is caused by the increase in the number of protons and electronsacross a period. One proton has a greatereffectthan one electron; thus, electrons are pulled towards the nucleus, resulting in a smaller radius. This is caused by electronshielding.
