The sum of electrons present in all sub shells of an atom with \(m_s\) value of \(+\frac{1}{2}\) for \(n=4\) and \(m_s\) value of \(-\frac{1}{2}\) for \(\mathrm{n}=3\) is
- A \(25\)
- B \(16\)
- C \(09\)
- D \(32\)
Answer & Solution
Correct Answer
(A) \(25\)
Step-by-step Solution
Detailed explanation
No. of electrons in ' \(n\) ' shell \(=2 n^2\) \(\therefore \mathrm{n}=4 ; 2 \mathrm{n}^2=32 \mathrm{e}\) and \(\mathrm{n}=3 ; 2 \mathrm{n}^2=18 \mathrm{e}\) Half of the electrons in one shell has \(\left(+\frac{1}{2}\right)\) spin and half of them has…
