Which of the following element has the largest atomic size?
Open in App
Solution
The correct option is B Rb
As we move down the group, new shells are being added in the elements due to which the distance between the outermost electrons and the nucleus increases. Thus, the atomic size increases on moving down the group in spite of the increase in nuclear charge.
