Explain the variation of atomic radii in a period moving left to right​

Explanation:

Atomic radius decreases from left to right within a period. This is caused by the increase in the number of protons and electrons across a period. One proton has a greater effect than one electron; thus, electrons are pulled towards the nucleus, resulting in a smaller radius. ... This is caused by electron shielding

Explanation:

along a period moving lift to right generally atomic radii decrease due to increase in proton but no of subshells remains constant hence net effective force by nucleus increase. in moving down the group no of shells get added and hence effective force on outer shells decreases due to which size increase.there may be some exceptions due to shielding effect and screening effect
