Question

What is the maximum number of electrons in the 4d subshell?

Answer 1

1. 4d subshell has five orbitals that are ${\mathrm{d}}_{\mathrm{xy}},{\mathrm{d}}_{\mathrm{yz}},{\mathrm{d}}_{\mathrm{zx},}{\mathrm{d}}_{{\mathrm{x}}^2-{\mathrm{y}}^2}\mathrm{and}{\mathrm{d}}_{{\mathrm{z}}^2}$.
2. Each d orbital can possess a maximum of two electrons.
3. So we can say 4d subshell has a maximum of 10 electrons.
4. The shape and orientation of these orbitals are shown below:
