Electron Configuration

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 orbitals.

Front

What is the Pauli Exclusion Principle?

Back

No two electrons in an atom can have the same set of four quantum numbers; this means that an 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 an orbital?

Back

A region in an atom where there is a high probability of finding electrons.

Front

What are the four types of orbitals?

Back

s, p, d, and f orbitals, each with different shapes and energy levels.

Front

Which orbital has the highest energy: s, p, d, or f?

Back

f orbital has the highest energy.

Front

What does each row on the periodic table represent?

Back

An energy level.

Front

What is the shape of an s orbital?

Back

Spherical.

Front

What is the shape of a p orbital?

Back

Dumbbell-shaped.
