Bohr Model and Quantum Mechanics

These flashcards cover key vocabulary and concepts related to the Bohr model, quantum mechanics, and the principles of electron behavior in atoms.

Bohr Model

A model of the atom that depicts electrons existing in quantized energy levels.

Photon

A quantum of light or electromagnetic radiation, which carries energy.

Rydberg Formula

Equations used to calculate the wavelength and energy transitions of electrons in hydrogen: 1/λ = 1.097x10^(-2) nm^(-1) (1/n1^2 - 1/n2^2) and ΔE = -2.178x10^(-18) J * (1/nf^2 - 1/ni^2).

Ionization Energy

The energy required to completely remove an electron from an atom.

De Broglie Wavelength

The wavelength associated with a moving particle, calculated using λ = h/(mv), where h is Planck's constant.

Heisenberg Uncertainty Principle

A principle stating that it is impossible to simultaneously know both the exact position and momentum of a particle.

Planck's Constant (h)

A fundamental constant valued at approximately 6.626x10^(-34) J*s, used in quantum mechanics.

Energy Transition

The change in energy levels of an electron within an atom as a result of absorbing or emitting photons.

Quantum Measurement

A measurement that shows inherent uncertainty due to the properties of quantum mechanics.
