Bohr Model and Electron Energy Levels

Problematic Assumptions: Early theories of energy suggested electrons could exist anywhere around the nucleus.
Consequence of Electric Fields: If electrons, being charged particles, moved continuously within an electric field, they would constantly emit energy.
- Over time, this energy loss would cause their orbits to degrade.
- Eventually, the electron would crash into the positively charged proton (nucleus).
- This implies atomic self-destruction, which is not observed.
Mathematical Inadequacy: There was no mathematical framework to justify arbitrary energy levels or stable orbits under classical physics.
- Classical theory suggested any orbit and thus any energy level should be possible, which contradicts experimental observations.

Rejection of Classical Model: Niels Bohr declared the classical view incorrect.
