Figure \(\PageIndex{4}\): The chart shows the energies of electron orbitals in a multi-electron atom. Figure \(\PageIndex{4}\) illustrates the energy levels for various orbitals. The number before the orbital name (such as 2s, 3p, and so forth) stands for the principal quantum number, n.

Read this tutorial to learn about electron shells, electron orbitals, and subshells, as well as electron configurations!
In chemistry and atomic physics, an electron shell may be thought of as an orbit that electrons follow around an atom's nucleus. The closest shell to the nucleus is called the "1 shell" (also called the "K shell"), followed by the "2 shell" (or "L shell"), then the "3 shell" (or "M shell"), and so on further and further from the nucleus.
14 Αυγ 2020 · Electron configurations and orbital diagrams can be determined by applying the Pauli exclusion principle (no two electrons can have the same set of four quantum numbers) and Hund’s rule (whenever possible, electrons retain unpaired spins in degenerate orbitals).
Electron shells 1n and 2n are full, containing two and eight electrons respectively, while electron shell 3n contains four electrons for a total of fourteen electrons. We said earlier that electron shells in an atom are usually filled in strict order, starting with the lowest energy level.
10 Αυγ 2022 · Building Atoms: Main Shells. An electron shell is the outside part of an atom around the atomic nucleus. It is a group of atomic orbitals with the same value of the principal quantum number \(n\). Electron shells have one or more electron subshells, or sublevels.
The Bohr model shows the atom as a central nucleus containing protons and neutrons, with the electrons in circular electron shells at specific distances from the nucleus, similar to planets orbiting around the sun.
