What Is the Bohr Model?
The Bohr model is an atomic model proposed by Danish physicist Niels Bohr in 1913. It depicts electrons orbiting the nucleus in fixed circular paths called electron shells, each at a specific energy level. While superseded by quantum mechanics, the Bohr model remains the essential first step for understanding atomic structure in chemistry education.
Shell Capacity Rules
- Shell 1 (K): Maximum 2 electrons
- Shell 2 (L): Maximum 8 electrons
- Shell 3 (M): Maximum 18 electrons
- Shell 4 (N): Maximum 32 electrons
- General formula: 2n² for shell n
How to Read a Bohr Diagram
- The nucleus (center) contains protons + neutrons
- Rings represent energy shells (K, L, M…)
- Dots on rings represent electrons
- Outermost electrons are valence electrons
- Valence count determines chemical behavior
