The increasing order of the atomic radii of elements Na- Rb- K- Mg is

Question

Toppr Admin · Accepted Answer

Correct option is D- -Mg On moving down the group- size of element increases due to addition of new shells- On moving from left to right across a period- size of element decreases due to addition of electrons in same shell and increase in effective nuclear charge-160-160-

The increasing order of the atomic radii of elements $$Na, Rb, K, Mg$$ is

Correct option is D. $$Mg < Na < K < Rb$$
On moving down the group, size of element increases due to addition of new shells. On moving from left to right across a period, size of element decreases due to addition of electrons in same shell and increase in effective nuclear charge.
