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.

Mar 23, 2026 · Atomic orbitals are regions around the nucleus where electrons are most likely to be found. These orbitals differ in shape, size, energy, and the number of electrons they can hold.

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 …

When a planet moves around the sun, you can plot a definite path for it which is called an orbit. A simple view of the atom looks similar and you may have pictured the electrons as orbiting around the …
