NEET · Chemistry · STD 11 - 2. structure of atom
What is the maximum numbers of electrons that can be associated with the following set of quantum numbers? \(n = 3, l = 1\) and \(m = {-1}\)
- A \(4\)
- B \(2\)
- C \(10\)
- D \(6\)
Answer & Solution
Correct Answer
(B) \(2\)
Step-by-step Solution
Detailed explanation
The orbital of the electron having \(=3, l=1\) and \(m=-1\) is \(3 p_{z}(\text { as } n / m)\) and an orbital can have a maximum of two electrons with opposite spins. therefore, \(3 \mathrm{p}_{z}\) orbital contains only two electrons or only \(2\) electrons are associated with \(\mathrm{n}=3, \mathrm{l}=1, \mathrm{m}=-1\)
