Question

atomic radius increasing down a group​

Answer 1

Answer:

True

The number of energy levels increases as you move down a group as the number of electrons increases. Each subsequent energy level is further from the nucleus than the last. Therefore, the atomic radius increases as the group and energy levels increase. 2) As you move across a period, atomic radius decreases.

Answer 2

Answer:

Yes it increase down a group because the atomic shells are also increasing.
