Rank from largest to smallest atomic radius. to rank items as equivalent, overlap them. a. mg b. p c. cl d. al e. ar

Mg > Al > P > Cl > Ar

Explanation:

Mg / P / Cl / Al / Ar

The tendency of atomic radia is that the higher the period, the higher the radius; and that the higher the group, the smaller the radius.

Mg is the furthest left and down between the options, so that's the largest one.Just right of Mg there's Al, so that's the next one.Going by the tendency, the next ones should be P and Cl.Ar is the furthest right, so that's the smallest one.
