Question

Give the values of n and ell for an electron in a 4d orbital. n = ell = 16 select the values of mell and ms that are possible for an electron in a 4d orbital. mell = −4 −3 −2 −1 −1/2 0 +1/2 1 2 3 4 ms = −4 −3 −2 −1 −1/2 0 +1/2 1 2 3 4

Answer 1

There are four quantum numbers: n, l, ml and ms. When the orbital is 4d, the 4 is corresponding to n. Thus, n=4. Then, the d corresponds to l = 2. Now, to find the value for ml, take the values of -l to +l. Therefore,

ml = -2, -1, 0, 1, 2

Then,ms could only be either +1 or -1.
