Question

as you move down a group in the periodic table, atomic size generally a. increases. b. decreases. c. remains the same. d. varies randomly.

Answer 1

increases is the answer

Answer 2

The atomic size / radius generally increases, as when we move down the group, it means that there is an additional shell compared to the last element. For example, K has one more electron shell than Na does, so the atomic size generally increases as we move down a group in the periodic table.
