Answer:
The energy level is 5.
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.
[tex]m_{l}[/tex] is a quantum number. It is define the number of energy level in a sub-shells .
[tex]m_{s}[/tex] is define the spin of the electron.
So, The quantum number is
[tex]m_{l}=-2,-1,0,1,2[/tex]
[tex]m_{s}[/tex] is [tex]+\dfrac{1}{2}[/tex] and [tex]-\dfrac{1}{2}[/tex] for every energy level.
The energy level is 5.
Hence, The energy level is 5.
