Which element below would have the largest atomic radius? *
Barium
Beryllium
Calcium
Magnesium

Expert Solution

Step 1

Generally in a periodic table form left to right in a period the atomic radius decreases while in a group from up to down, the atomic radius increases. In a period the shell Number will be fix but nuclear charge increases,which is responsible for decrease atomic radius in a period. While in a group atomic radius increases because number of shells increases, and nuclear charge becomes less effective as compared to electron - electron repulsion.
