CHEM 1211 Section 3.4 (The Hydrogen Spectrum and the Bohr Model)

Bohr Model of the Atom

A model for the atom proposed by Niels Bohr where electrons are found at specific distances from the nucleus in orbits, travelling in circular paths with discrete energy levels.

Ground State

the lowest energy level, closest to the nucleus

Excited State

when electrons absorb energy and move to higher levels called excited states

energy

Electrons in excited states will emit ______ to return to the more stable ground state.

Rydberg Equation

a mathematical equation that predicts the wavelength of light emitted or absorbed when an electron transitions between energy levels

transition

Electrons will __________ between energy levels when absorbing or emitting energy.

Absorption

the process of exciting electrons to higher states using light

Emission

The relaxation of electrons back to lower states

light emission profile

Each element has a unique _____ ________ _______ due to it’s unique electronic levels.

Wave-Particle Duality

Light can be described as both waves and particles
