WEBJan 31, 2024 · The Aufbau Principle (also called the building-up principle or the Aufbau rule) states that, in the ground state of an atom or ion, electrons fill atomic orbitals of the lowest available energy level before occupying higher-energy levels.
WEBWhat is the Aufbau Principle? The Aufbau principle dictates the manner in which electrons are filled in the atomic orbitals of an atom in its ground state. It states that electrons are filled into atomic orbitals in the increasing order of orbital energy level.
WEBThe Aufbau principle (/ ˈ aʊ f b aʊ /, from the German Aufbauprinzip, which means "building-up principle"), also called the Aufbau rule, states that in the ground state of an atom or ion, electrons first fill subshells of the lowest available energy, then fill subshells of higher energy. For example, the 1s subshell is filled before the 2s ...
WEBThe Aufbau principle states that electrons fill lower-energy atomic orbitals before filling higher-energy ones (Aufbau is German for "building-up"). By following this rule, we can predict the electron configurations for atoms or ions.

WEBUpdated on August 31, 2019. Stable atoms have as many electrons as protons in the nucleus. The electrons gather around the nucleus in quantum orbitals following four basic rules called the Aufbau principle . No two electrons in the atom will share the same four quantum numbers n , l , m, and s.
WEBSep 20, 2022 · The Aufbau principle gives the order of electron filling in an atom. It can be used to describe the locations and energy levels of every electron in a given atom.
