Question

For the n = 3 electron shell, which of the following quantum numbers are valid? Check all that apply.

Answer 1

this is the answer on edgeunity i=0,m=-2,m=2

Answer 2

Answer: l=0, m= -2, m=2 are all valid.

Explanation: The given value on n =3, that is the principal quantum number or the main energy level for the electron is 3 i.e. M shell.

For a given value of n, the possible values of azimuthal quantum number (l) are 0 to n-1.

Thus possible values of l are = 0, 1 , 2

Also for a given value of l, the possible values of magnetic quantum number (m) are = l to -l

Thus  for l=0 possible values of m is 0  ,  for l = 1 possible values of m are -1, 0 and 1 , for l= 2 possible values of m are -2, -1, 0, 1, 2
