Bohr Model and Atomic Energy Levels

Flashcards covering vocabulary related to the Bohr model and atomic energy levels.

Bohr Model

Model of the atom where electrons orbit the nucleus in specific paths.

Absorption

Occurs when an atom absorbs a photon and moves to a higher energy level.

Emission

Occurs when an atom drops from a higher energy level to a lower one, emitting a photon.

Ionization Energy

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

Ground State

The lowest possible energy state of an atom.

Excited States

States of higher energy than the ground state.

Bohr’s Correspondence Principle

The principle that quantum theory results must tend asymptotically to those obtained from classical mechanics in the limit of large quantum numbers.

Hydrogen-like Atoms

Atoms that have only one electron, similar to hydrogen (e.g., He+, Li2+).

Atomic Energy Levels

Energy levels within an atom that are discrete and specific, rather than continuous.

Bohr Frequency Rule

The rule stating that an atom radiates energy (a photon) only when it makes a transition from one stable orbit to another.

Planck's Constant

The constant used in atomic physics, relating the energy of a photon to its frequency. Symbol: h

Quantization of Angular Momentum

The angular momentum of a particle in a circular orbit is restricted to specific values.

Collisional Excitation

Atoms gain energy through collisions with other atoms or electrons.

Thermal Excitation

Atoms receive energy by thermal excitation through collisions between atoms.

Reduced Mass

Taking nuclear motion into account by replacing the mass of the electron with a reduced mass.

Rydberg Constant

The constant relating to atomic spectra, accounting for the mass of the nucleus. Symbol: RH

Hydrogen Ion

The positively charged ion of hydrogen after an electron is removed.
