Electron shell - Wikipedia
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.

2022年6月24日 · Chemists use an electron configuration to represent the organization of electrons in shells and subshells in an atom. An electron configuration simply lists the shell and subshell labels, with a right superscript giving the number of electrons in that subshell. The shells and subshells are listed in the order of filling.
7.2: Atomic Subshell Energies and Electron Assignments
In essence, you can think of electrons filling in "n+ l " order. If you have an equal "n + l" value for two orbitals, then electrons will occupy the orbital with the lower "n" value. The following figure illustrates the energy orbitals for each subshell and their filling order according to …
Shell - Electron - Character, Definition, subshell, energy of subshell ...
The order of energy of the subshell. The filling of the shells and subshells with electrons proceeds from subshells of lower energy to subshells of higher energy. This follows the Aufbau principle. According to this subshells with a lower n + ℓ value are filled before those with higher n + ℓ values.
4.1 Electronic Structure of Atoms (Electron Configurations)
Each added electron occupies the subshell of lowest energy available (in the order shown in Figure 4.1.1). Electrons enter higher-energy subshells only after lower-energy subshells have been filled to capacity. Figure 4.1.3 illustrates the traditional way to …
Electron Shell - Definition & Number of Electrons in Each Shell
2024年5月9日 · When electrons are filled in the subshells, they proceed from subshells of lower energy to higher energy, following the Aufbau principle. The electrons follow the ‘n + ℓ’ rule, also known as the Madelung rule. Here, ‘n’ stands for the principle quantum number, whereas ‘ℓ ‘represents the azimuthal quantum number.

Organization of Electrons in Atoms – Introductory Chemistry – …
Electrons are typically organized around an atom by starting at the lowest possible quantum numbers first, which are the shells–subshells with lower energies. Consider H, an atom with a single electron only.
Electron configurations - chem.uic.edu
There are at least three methods to predict electron configurations that work most of the time. Memorizing the sequence is attractive to some people. I prefer to use a method based on the periodic table. The subshells in atoms "generally" follow this order for filling: You need to remember the limits on each type subshell.
