Question

After a magnetic field is applied, how many energy levels would you expect for then=3,ℓ=2 state, including electron spin?

Answer 1

The energy level is 5.

Step-by-step explanation:

Given that,

n = 3

l = 2

We know that,

l shows the number of sub-shells and define the number of angular nodes.

n shows the number of electron shell.

`m_(l)` is a quantum number. It is define the number of energy level in a sub-shells .

`m_(s)` is define the spin of the electron.

So, The quantum number is

`m_(l)=-2,-1,0,1,2`

`m_(s)` is
`+(1)/(2)` and
`-(1)/(2)` for every energy level.

The energy level is 5.

Hence, The energy level is 5.
