What is electron configuration?

Back

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

What is the electron configuration for fluorine?

Back

1s² 2s² 2p⁵

Front

What is Hund's rule?

Back

Every orbital in a subshell is singly occupied before any orbital is doubly occupied, and all singly occupied orbitals have the same spin.

Front

What is the Pauli exclusion principle?

Back

No two electrons in an atom can have the same set of four quantum numbers.

Front

What is the significance of the periodic table groups?

Back

Elements in the same group have similar chemical properties and the same number of valence electrons.

What is the electron configuration for Vanadium (V)?

Back

[Ar] 4s² 3d³

Front

What is orbital notation?

Back

A representation of the electron configuration of an atom using arrows to indicate the spin of electrons in orbitals.

Front

What is the maximum number of electrons that can occupy a single orbital?

Back

Two electrons, with opposite spins.

Front

What is the Aufbau principle?

Back

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