🤓 Based on our data, we think this question is relevant for Professor Hamilton & Bass' class at UMBC.

Solution: Which set of three quantum numbers does not specify an orbital in the hydrogen atom? Provide step by step explanation.a. n = 2; l = 1; m l = -1b. n = 3; l = 2; m l = 2c. n = 2; l = 0; m l = 0d. n = 3; l = 4; m l = 0

Problem

Which set of three quantum numbers does not specify an orbital in the hydrogen atom? Provide step by step explanation.

a. n = 2; l = 1; m l = -1

b. n = 3; l = 2; m l = 2

c. n = 2; l = 0; m l = 0

d. n = 3; l = 4; m l = 0

Solution

To solve this problem, let’s first define the values of the first three quantum numbers:

 principal quantum number (n)  energy level in orbitals and its value could be any positive integer starting from 1 to infinity

 angular momentum quantum number ((l) has to be at least 1 less than n, range of values from 0 up to (n-1)

• magnetic quantum number (m) → range of values from - to +.
