Question
In which part of a group would you separately expect the elements to have the largest atomic size?
Advertisements
Solution 1
The largest atomic size is found at the bottom of the group, as the atomic size increases on moving down in a group of the periodic table.
Solution 2
The largest atomic size can be expected in the lower part of the group.
