Answer 2

Answer:

Let me give you some details of quantum numbers...

Principal quantum number(n) has its value 1, 2, 3.......

Azimuthal quantum number(I)which has it's value from 0 to (n-1).

Magnetic quantum number(m),whose value ranges from negative I to positive I.

Spin quantum numbers(s),which determines the spin of an electron.

Consider an example

In n=2 (L shell)

I=0 (2s), 1 (2p)

m=0 (for 1=0) and -1 ,0 ,1(for I=1)

Now according to your question m=-3,which is possible when I =3 and ,I=3 is possible when n=4

So the principal quantum number is 4.
