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:
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
