Bohr Diagrams

Bohr Model

- Atoms are electrically neutral
- Two different models can be used to describe electron configuration

1. Energy level model
2. Bohr model

- Electrons occupy shells which are divided into orbitals

1.  2e− in the first orbital
2.  8e− in the second orbital
3.  8e− in the third orbital  

Energy level model for Argon.



Protons = 18
Neutrons = 22
Electrons = 18

Protons = 8
Neutrons = 8
Electrons = 16
