Current Question (ID: 18884)

Question:

$\text{An actinoid that does not have one electron in its 6d orbital is -}$

Options:

1. $\text{U (Atomic number. 92)}$
2. $\text{Np (Atomic number. 93)}$
3. $\text{Pu (Atomic number. 94)}$
4. $\text{Cm (Atomic number. 96)}$

Solution:

$\text{The electronic configuration of U, Np, Pu, and Cm are as follows:}$ $\text{U = 92, [Rn] 5f}^3 \text{ 6d}^1 \text{7s}^2$ $\text{Np = 93, [Rn] 5f}^4 \text{6d}^1 \text{ 7s}^2$ $\text{Pu = 94, [Rn] 5f}^6 \text{ 7s}^2$ $\text{Cm = 96, [Rn] 5f}^7 \text{ 6d}^1 \text{7s}^2$ $\text{Thus, Pu does not have electron in 6d orbital.}$ $\text{Hence, option third is the correct answer.}$
