The electrons in an atom are arranged in shells that surround the nucleus, with each successive shell being farther from the nucleus. Electron shells consist of one or more subshells, and subshells consist of one or more atomic orbitals.
Shells, subshells, and orbitals. Introduction to electron configurations. The Aufbau principle. Valence electrons. Electron configurations of ions. Electron configurations of the 3d transition metals. Atomic structure and electron configuration.

Electron orbitals (basics): what are electron orbits? Attraction, repulsion, nucleus, s-orbitals and p-orbitals. Free A-level and IB Chemistry Notes, Resources and Tutorials
20 Μαΐ 2021 · 20 May 2021. Electron Orbitals. Each shell can be divided further into subshells, labelled s, p, d and f. Each subshell can hold a specific number of orbitals: s subshell : 1 orbital. p subshell : 3 orbitals labelled p x, p y and p z. d subshell : 5 orbitals. f subshell : 7 orbitals.
13 Μαρ 2018 · The first, the principle quantum number, demonstrates the energy level of the atom represented by its electron shells. The second, the orbital quantum number, demonstrates the electron subshells, or the particular configurations electrons take in three dimensions.
Now, electron orbitals are really defined as three-dimensional regions around the nucleus of an atom where electrons can be found. Although electron orbitals are three-dimensional regions, they can still be envisioned in two dimensions as energy shells.
