Question
How many 4d electrons can have spin quantum number $-\frac{1}{2}?$ Explain.
✓

Answer

Five 4d electrons can have spin quantum number $-\frac{1}{2}$ because there are total 10 electrons in d-orbitals, out of which five will have $+\frac{1}{2}$ and other five will have $-\frac{1}{2}$ spin quantum numbers.
