Atomic orbitals are basic building blocks of the atomic orbital model (or electron cloud or wave mechanics model), a modern framework for visualizing submicroscopic behavior of electrons in matter.

Explore atomic orbitals—s, p, d, and f shapes—and how they describe electron behavior in the modern atomic model. Includes visuals and key characteristics.

Orbitals with l = 0 are called s orbitals (or the s subshells). The value l = 1 corresponds to the p orbitals.

Feb 2, 2023 · Learn about atomic orbitals with diagrams of their types, shapes, energy, and a chart of their filling orders.

That probability cloud is called an orbital (not orbit): Orbital: a region where there is a 90% chance of finding an electron. The simplest orbital is the "s" orbital (such as the single electron in Hydrogen): …

There are four types of orbitals that you should be familiar with s, p, d and f (sharp, principle, diffuse and fundamental). Within each shell of an atom there are some combinations of orbitals.

Feb 9, 2026 · Atomic orbitals are commonly designated by a combination of numerals and letters that represent specific properties of the electrons associated with the orbitals—for example, 1 s, 2 p, 3 d, 4 f.

Atomic orbitals are defined as regions in space around an atomic nucleus where the probability of finding an electron is high, corresponding to specific combinations of quantum numbers. Each atomic …

This page discusses atomic orbitals at an introductory level. It explores s and p orbitals in some detail, including their shapes and energies. d orbitals are described only in terms of their energy, and f …

In contrast to his concept of a simple circular orbit with a fixed radius, orbitals are mathematically derived regions of space with different probabilities of containing an electron. One way of representing …
