प्रश्न
How many electrons will be present in the sub-shells having ms value of - 1/2 for n = 4?
उत्तर
Number of orbitals in the nth shell = n2
For n = 4
Number of orbitals = 16
If each orbital is taken fully, then it will have 1 electron with ms value of `- 1/2`
∴ Number of electrons with ms value of `(-1/2)` is 16.
