Quizplus · Accepted Answer

Atomic radius generally increases down a group and decreases across a period in the periodic table. Since Ca is in Group 2 and the others are in Group 4-6 of the same period, Ca has the largest atomic radius. Among Ti, V, and Cr, the atomic radius decreases from Ti to Cr.
