bohr model

Bohr Model

A model of the atom that describes electrons as being in specific orbits around the nucleus, based on the interaction of matter and electromagnetic radiation.

Quantum Theory

The theory that explains the emission or absorption of radiation by electrons in fixed amounts called quanta.

Frequency

The number of complete waves that pass a point in one second, measured in hertz (Hz).

Wavelength

The distance between adjacent crests or troughs of a wave, measured in meters (m).

Ground State

The lowest energy state of an electron in an atom.

Excited State

When an electron absorbs energy and moves from a lower energy level to a higher energy level.

Photon

A quantum of light emitted or absorbed by an electron when it transitions between energy levels.

Electromagnetic Waves

Waves that consist of oscillating electric and magnetic fields and can travel without a medium.

Spectral Lines

The series of lines representing the discrete wavelengths of light emitted or absorbed by an electron transitioning between energy levels.

Limitations of Bohr Model

The model cannot explain the emission spectra of multi-electron systems, only that of hydrogen.
