What is the Aufbau Principle in electron configurations?

Back

The Aufbau Principle states that electrons occupy the lowest energy orbitals first before filling higher energy levels.

Front

What are orbitals in the context of electron configurations?

Back

Orbitals are regions in an atom where there is a high probability of finding electrons.

Front

What is the difference between s, p, d, and f orbitals?

Back

s orbitals are spherical, p orbitals are dumbbell-shaped, d orbitals have more complex shapes, and f orbitals are even more complex.

What is the significance of the Pauli Exclusion Principle in electron configurations?

Back

The Pauli Exclusion Principle states that no two electrons in an atom can have the same set of four quantum numbers.
