Question

How atomic radius is related to no. of shells ​

Answer 1

$\huge\mathbb\orange{Hello!!}$

As the atomic number increases along each row of the periodic table, the additional electrons go into the same outermost shell; whose radius gradually contracts, due to the increasing nuclear charge.

Therefore, atomic radius decreases.

Answer 2

$\huge{ \boxed{ \boxed{ \underline{ \mathbb{ \red{ANSWER}}}}}}$

∆ Atomic Radius is directly proportional to the Atomic radius.

∆ Higher the no. of shells higher will be the Atomic radius.
