In this question we are assigning with the task to find out the value which is not allowed.
00:08
Magnetic quantum number is represented by term ml.
00:12
Before getting into the question, let us understand what is n, l and ml.
00:18
N is the principal quantum number for an atom and l is angular momentum quantum number.
00:33
And finally comes m which is magnetic quantum number.
00:38
And we have another quantum number that has been quantum number and it's not discussed in this question.
00:44
If n is equal to x, then l will have a value of n minus 1, that is x minus 1.
00:55
Let us say, if the value of n is equal to 7, as given in the question, l is 7 minus 1, which is 6...
