Atoms are the basic units of matter that make up everyday objects. Atoms are made up of three subatomic particles: protons, neutrons, and electrons. Atoms can combine to form molecules, which are the building blocks of all living things.

Electron configuration is the arrangement of electrons in an atom or molecule according to the principles of quantum mechanics. The Pauli exclusion principle states that two electrons in an atom cannot have the same set of quantum numbers. The Aufbau principle states that electrons fill the lowest energy orbitals first, and electrons will fill orbitals of equal energy in order of increasing size.

The first electron shell can only hold a maximum of 2 electrons, while the second shell can hold up to 8 electrons. The electron configuration of an atom can be used to predict its chemical properties. The orbitals of electrons in an atom can be represented using 3-dimensional diagrams called orbital diagrams.
