Neet Solved Paper 2013 Question 2

Question: 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

Options:

A) 10

B) 6

C) 4

D) 2

Show Answer

Answer:

Correct Answer: D

Solution:

The orbital of the electron having n = 3,

$ l=1 $ and m = - 1 is $ 3p _{z} $ $ (as,nl _{m}) $ and an orbital can have a maximum of two electrons with opposite spins

$ \therefore $ $ 3p _{z} $ orbital contains only two electrons or only 2 electrons are associated with n = 3, $ l=1,,m=-1. $
