Electron Configuration and Orbital Notation

Front

What is electron configuration?

Back

The distribution of electrons in an atom's orbitals, indicating the energy levels and sublevels occupied by electrons.

Front

What does the Aufbau principle state?

Back

Electrons occupy the lowest energy orbitals first before filling higher energy levels.

Front

What is the Pauli exclusion principle?

Back

No two electrons in an atom can have the same set of four quantum numbers; each orbital can hold a maximum of two electrons with opposite spins.

Front

What is Hund's rule?

Back

Electrons will fill degenerate orbitals (orbitals of the same energy) singly before pairing up.

Front

What is the significance of the 1s, 2s, 2p, etc. in electron configuration?

Back

These notations represent the different energy levels and types of orbitals where electrons are found.

Front

What is a ground state electron configuration?

Back

The lowest energy arrangement of electrons in an atom.

Front

What happens when an electron moves from an excited state to a ground state?

Back

The atom emits energy, often in the form of light.

Front

What is the definition of a wave's amplitude?

Back

The maximum distance from the rest position to the crest or trough of a wave.

Front

What is a trough in a transverse wave?

Back

The lowest point of a wave, opposite to the crest.

Front

What is the definition of wavelength?

Back

The distance between two consecutive crests or troughs in a wave.
