Question

General electronic configuration for s- block element is

• A. $\left[inertgas\right]n{s}^{\text{0-1}}$
• B. $\left[inertgas\right]n{s}^{\text{0-2}}$
• C. $\left[inertgas\right]n{s}^{\text{1-2}}$
• D. All of the above

Answer 1

The correct option is C $\left[inertgas\right]n{s}^{\text{1-2}}$

In s block elements, the last electron enters in the s subshell and s orbital can occupy a maximum of two electrons. So, general configuration for s - block will be $\left[inertgas\right]n{s}^{\text{1-2}}$.
