Question

The general electronic configuration of representative elements is________

• A. $n{s}^{1-2}n{p}^{1-6}$
• B. $n{s}^{1-2}n{p}^{1-5}$
• C. $n{s}^{1-2}(n-1)p^{1-5}$
• D. $n{s}^{1-2}(n-1)p^{1-6}$

Answer 1

Answer: (B)

$n{s}^{1-2}n{p}^{1-5}$

The elements of "s" and "p" blocks except "d" group elements are called as representative elements.

"s" orbital can have a maximum of two electrons because "s" block has two groups.
They are $n{s}^{1-2}$.

The electronic configuration of "p" block representative elements varies from $n{s}^{2}n{p}^1$ to $n{s}^{2}n{p}^5$.
