Overview
The Bohr model is a quantum model of the atom where electrons move in circular orbits around the nucleus. While replaced by modern quantum mechanics, it accurately predicts the spectral lines of hydrogen-like atoms.
💡
Pro Tips
n = 1 refers to the ground state (lowest energy).
Hydrogen-like atoms have only one electron (e.g., H, He+, Li++).
Energy is negative because the electron is bound to the nucleus.

Fun Facts
"The Bohr model successfully explained the Rydberg formula for hydrogen spectral lines."
"The 'Bohr radius' (a₀) is about 0.529 Ångströms."
"In the Bohr model, electrons jumping between orbits emit or absorb photons of specific energies."
