Quantum Numbers And Orbitals

Maximum number of electrons in a shell is given by: Out of these, half will have spin :

The maximum number of electrons in an orbit is given by the formula , where n is the principal quantum number. For n = 6, the maximum number of electrons is .

Quantum numbers follow these rules:
- Principal quantum number:
- Azimuthal quantum number:
- Magnetic quantum number:
- Spin quantum number:
In option (3), can be 0, 1, or 2. But is invalid for , so this option is not possible.
