Question

The transition elements have a characteristic electronic configuration which can be represented as:

• A. $(n-2)s^2{p}^6{d}^{1-10}(n-1)s^2{p}^{6}n{s}^2$
• B. $(n-2)s^2{p}^6{d}^{1-10}(n-1)s^2{p}^6{d}^{1-2}n{s}^1$
• C. $(n-1)s^2{p}^6{d}^{10}n{s}^{2}n{p}^{6}n{d}^{1-10}$
• D. $(n-1)s^2{p}^6{d}^{1-10}n{s}^{1-2}$

Answer 1

The correct option is D $(n-1)s^2{p}^6{d}^{1-10}n{s}^{1-2}$

The transition elements are those which have partially filled d orbitals in their common oxidation state.

$(n-1)s^2{p}^6{d}^{1-10}n{s}^{1-2}$ is the general electronic configuration of transition element. Atoms with half-filled or completely filled d orbitals will be having more stability.
