Answer 1

3,3,-1, -1/2 is not possible. in generally if n = l is given that is not possible.

We know the 4 quantum numbers Principal quantum number (n): n gives the information of orbit K, L, M, N... n values are 1,2, 3, 4, 5, ............ Azimuthal quantum number () The value of e = (n-1), the values are 0,1,2,3........... upto (n-1) 1 tells about the number of sub shells, shape of sub shells. If = 0, s sub shell { = 1, p sub shell. { = 2, d sub shell Magnetic quantum number (m) Magnetic quantum number gives the orientation of subshells. The value of m varies from - to +{ through 0. For example: 4 = 2. Then me vales are -2, -1, 0, 1, 2. Spin quantum number (m) The value of m, is +1/2 or 1/2. Spin may be clock wise or anti clock wise. Given data Possibility reason ", mim. 2 1 0 -1/2 Possible 33-1-1/2 not possible n=1, then ( =0, then my = 0, spin may be +1/2 or -1/2 n=3, then < =0,1,2 But given i =3, so not possible n=3, then l =0,1,2 and l =0 mı = 0, spin may be +1/2 or -1/2 n=2, then l =0,1 and l=1 m = -1, 0, +1 spin may be +1/2 or -1/2 0 0 +1/2 Possible -1 +1/2 Possible
