Which stalement about the quantum numbers that identify an atomic orbital is not correct? Select one o a. For p orbitals of any given shell, there are five possible m, values. b The magnetic quantum number, m, identifies the orientation of the orbital in space. An sorbital of any given shell has only one possible m, value ed The magnetic quantum number can have values that range from to in integer steps

Answer 1

Option a is the correct answer as it is not the correct statement.

Explanation:-

The value of m is determined by the value of l and the value of l for orbitals are 0 for s, 1 for p, 2 for d and 3 for f. Now, the value of m = 2l + 1

If we put the value of l for p I.e., 1 we get m = 2×1 + 1 = 3.

Therefore the first statement is not correct which is the answer to the question.

The magnetic quantum number m identifies the orientation of orbital in space. Ergo, b is not the right answer as the statement is correct.

For s orbital there is only one possible value that is 0. From the formula m = 2l + 1 where l = 0 for s and m = 1. Therefore the statement is correct.

The value of m determine the number of possible orientation in space the exact orientation is determined by moving from +l to -l in integer step. For example m for p orbital is 3 then it's values are +1, 0, -1.

For s m = 1 then it's value is 0 as value of l for s is 0.
