Study Notes
Bohr Model
- Bohr's atomic model aimed to refine Rutherford's model
- Electrons orbit the nucleus in specific, defined circular paths
- These orbits have specific energy levels, known as main energy shells or main energy levels
- The attraction between the nucleus and the electron counteracts the outward force of the electron's motion
- Electrons can transition between energy levels by absorbing or emitting a specific amount of energy (ΔE)
- The angular momentum of an electron in an orbit is quantized, meaning it must be a whole-number multiple of $\frac{h}{2\pi}$
- This is expressed mathematically as: $mvr = \frac{nh}{2\pi}$ where $m$ is mass, $v$ is velocity, $r$ is radius, and $h$ is Planck's constant
