Maximum Number of Electrons in a Subshell

Maximum Number of Electrons in a Subshell

### Formula:

$$\text{Maximum electrons}=2(2l+1)$$

### Terminologies:

- l → Azimuthal quantum number.

- 2l+1 → Number of orbitals in a subshell.

- Electron capacity → Maximum electrons that can occupy a subshell.

### Usage:

- Used to calculate electron capacity of s, p, d, and f subshells.
