What is the atomic orbital diagram for the ground state electronic configuration of chlorine?

The ground state electronic configuration of chlorine (Cl) is 1s² 2s² 2p⁶ 3s² 3p⁵. To complete the atomic orbital diagram for chlorine, follow these steps:

1. 1s Orbital: Fill the 1s orbital with 2 electrons. This is the lowest energy level.
2. 2s Orbital: Fill the 2s orbital with 2 electrons.
3. 2p Orbital: Fill the 2p orbital with 6 electrons. The 2p orbital has three sub-orbitals (2p_x, 2p_y, 2p_z), each of which can hold 2 electrons.
4. 3s Orbital: Fill the 3s orbital with 2 electrons.
5. 3p Orbital: Fill the 3p orbital with 5 electrons. The 3p orbital also has three sub-orbitals (3p_x, 3p_y, 3p_z), but since chlorine has only 5 electrons in the 3p orbital, one of the sub-orbitals will have only 1 electron.

Here is a simplified representation of the atomic orbital diagram for chlorine:

1s: ↑↓
2s: ↑↓
2p: ↑↓ ↑↓ ↑↓
3s: ↑↓
3p: ↑↓ ↑↓ ↑

In this diagram, each arrow represents an electron, and the direction of the arrow indicates the electron’s spin. The 3p orbital has one unpaired electron, which is characteristic of chlorine’s ground state configuration.
