Question

The electronic configuration of transition elements is:

• A. $n{s}^1$
• B. $n{s}^{2}n{p}^5$
• C. $n{s}^2(n-1)d^{10}$
• D. $(n-1)d^{1-10}n{s}^{0-2}$

Answer 1

The correct option is D $(n-1)d^{1-10}n{s}^{0-2}$

The electronic configuration of transition elements is given by $n{s}^{0-2}(n-1)d^{1-10}$. This is because there is a possibility that an electron from the 's' orbital jumps into the 'd' orbital in certain cases, in order to increased stability.

Hence, option D is the right answer.
