Which of the following statement is//are not correct ?

Options

A. The shape of an atomic orbit depends on the azimuthal quantum number
B. The orientation of an atomic orbit depends an the magnetic quantum number
C. The energy of an electron in an atomic orbit of a multi electron atom depends as on the principal quantum number
D. The number of atomic orbital of one type depends on the values of principal azimuthal and magnetic number

Explanation

To determine which statements are not correct, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Statement A:** "The shape of an atomic orbit or orbital depends on the azimuthal quantum number."
- **Analysis:** This statement is correct. The azimuthal quantum number (l) determines the shape of the orbital. For example, l = 0 corresponds to an s orbital (spherical shape), l = 1 corresponds to a p orbital (dumbbell shape), and so on.

2. **Statement B:** "The orientation of an atomic orbit depends on the magnetic quantum number."
