Question

Among the elements with the following electronic configurations, the one with the largest radius is [Ne] 3s [Ne] 3823p [Ne] 3s 3p3 [Ne 3s23p​

Answer 1

happy inpendence day ok

Answer 2

$\huge\frak\red{Answer}$

• Atomic radius is inversely proportional to Z-effective. Z-effective increases with increase in number of protons. Thus, atomic radius decreases on going from left to right in a period.

So, [Ne]3s 2 has the largest radius.
