Question

Incorrect match of general electronic configuration?

• A. $\left(\right.n-2\left.\right)f^{1 - 14}\left(\right.n-1\left.\right)d^{0 - 1}\left(ns\right)^{2}=f$ -block elements
• B. $\left(\right.n-1\left.\right)s^{2}p^{6}\left(ns\right)^{1 - 2}=s$ -Block elements
• C. $ns^{2}np^{1 - 6}$ Representative elements
• D. $\left(\right.n-2\left.\right)f^{1 - 14}\left(\right.n-1\left.\right)d^{1 - 10}\left(ns\right)^{2}=d$ -Block elements

Answer 1

Answer: (D)

The general configuration are as follows.
1. For $f$ block elements $\left(\right.n-2\left.\right)f^{1 - 14}\left(\right.n-1\left.\right)d^{0 - 1}\left(ns\right)^{2}$
2. For $d$ block elements $\left(\right.n-1\left.\right)d^{1 - 10}\left(ns\right)^{2}$
3. For representative elements $ns^{2}np^{1 - 6}$
4. For $s$ block elements $\left(\right.n-1\left.\right)s^{2}p^{6}\left(ns\right)^{1 - 2}$
