Bohr Model and Line Spectra

These flashcards cover key concepts related to the Bohr model of the atom, line spectra, and pertinent equations regarding electron energy levels.

Line Spectra

The light emitted from atoms and molecules, consisting of distinct lines representing specific wavelengths.

Bohr Model

A model of the atom where electrons exist in specific energy levels (n=1, 2, 3, etc.).

Emission Line

A bright line in a spectrum representing a single wavelength emitted by an atom.

Quantization

The concept that energy exists in discrete units or packets, proposed by Max Planck.

Photon

A quantum of light or electromagnetic radiation, associated with the electromagnetic field.

Energy Level (n)

A specific level of energy that an electron can occupy in an atom; the value of n indicates the size and energy of the level.

n=1, n=2, n=3

Represent the first, second, and third energy levels of an electron in an atom, respectively.

Energy Release

The process by which an electron emits energy in the form of a photon when it transitions to a lower energy level.

DDE Equation

The equation DDE = 2.18 x 10^-18J(1/ni^2 - 1/nf^2) used to calculate the energy difference between two energy levels.

En = -2.18 x 10^-18 J (1/n^2)

The equation that determines the energy of an electron at a specific energy level (n) in the Bohr model.
