Bohr

Definition

Bohr refers to Niels Bohr, a physicist who developed the Bohr model of the atom. This model introduced the idea of quantized energy levels for electrons within an atom.

5 Must Know Facts For Your Next Test

1. The Bohr model explains electron transitions between energy levels resulting in the emission or absorption of photons.
2. It incorporates Planck's quantum theory, which states that energy is quantized in discrete units called quanta.
3. Bohr's model was fundamental in explaining the spectral lines of hydrogen.
4. Electrons in the Bohr model occupy specific orbits with fixed radii and energies.
5. The stability of these electron orbits is due to the balance between electrostatic forces and centripetal forces.
