Question

Maximum number of electrons that can be associated with the set of quantum numbers
n=4 ,l= 2 , m =-1 , s=+1/2​

Answer 1

Answer:

One only

Explanation:

In 4d orbital, only two electrons have m=-1 , each with opposite spins, hence only one electron has + spin

Answer 2

The maximum number of electrons that can be associated with the given set of quantum numbers  (n = 4, l = 2, m = -1, s = +1/2) ​is ONE.

- This is in accordance with Pauli's Exclusion principle which states that no two electrons can have the same set of all four quantum numbers.

- The subshell with quantum numbers n = 4 and l = 2 is 4d.

- Out of the five 4d orbitals, only 1 orbital has m = -1.

- It can occupy a maximum of 2 electrons.

- Out of those 2 electrons, one has spin +1/2 and the other has -1/2.
