We’re being asked to determine the incorrect statement among the choices
Recall that the quantum numbers that define an electron are:
• Principal Quantum Number (n): deals with the size and energy of the atomic orbital.
The possible values for n are 1 to ∞.
• Angular Momentum Quantum Number (l): deals with the shape of the atomic orbital.
The possible values for l are 0 to (n – 1).
• Magnetic Quantum Number (ml): deals with the orientation of the atomic orbital in 3D space.
The possible values for ml is the range of l: –l to +l.
Which statement about quantum numbers is incorrect? Answer (e) if they are all correct or all incorrect.
a. The principal quantum number cannot equal zero.
b. When n = 3, the angular quantum number can be equal to 0, 1, or 2.
c. For an angular quantum number equal to 1, the magnetic quantum number can be +1, 0, o-1.
d. For any value of the angular quantum number (l), there are 2(2l+1) values of the magnetic quantum number.
e. All the above statements are correct or all are incorrect.
