Question

Explain why the size of the atom increases down the group of periodic table?​

Answer 1

Explanation:

When moving down a group of the periodic table, the atomic radius increases because of the presence of additional principal energy levels, which are further away from the nucleus.

Answer 2

Answer:

while going down a group the number of shells goes on increasing. therefore the distance between the nucleus and the valence electron increases. this results in increasing the atomic size of the atom
