Question

General electronic configuration of s-block elements is ______

• A. $1s^{1-2}$
• B. $2s^2$
• C. $1s^1$
• D. $n{s}^{1-2}$

Answer 1

Answer: (D)

$n{s}^{1-2}$

S can have only at maximum 2 electron in the orbital

Because it has l value as 0 hence we will have m values from -l to +l.here we have only one m value.

Hence only two electron.

Hence $n{s}^{1-2}$.

Option D is correct.
