How many electrons in an atom can have the following quantum

numbers?

n = 5, l = 2, ml = - 2, ms = + 1/2

The answer for the following question is explained.

Therefore the number of electrons present with the values n = 5, l = 2, m = - 2, s = + 1/2 is one (1).

Explanation:

Here;

n represents the principal quantum number

l represents the Azimuthal quantum number

m represents magnetic quantum number

s represents spin quantum number

n = 5,

l = 2,

m = - 2,

s = + 1/2

Here, it implies 5d orbital.

In the 5d orbital, 10 electrons.

As the magnetic quantum number is - 2, and so it can have 1 electron.

Therefore the number of electrons present with the values n = 5, l = 2, m = - 2, s = + 1/2 is one (1)
