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.
en.wikipedia.org/wiki/Electron_shellA full valence shell is the most stable electron configuration. Elements in other groups have partially filled valence shells and gain or lose electrons to achieve a stable electron configuration. An atom may give, take, or share electrons with another atom to achieve a full valence shell, the most stable electron configuration.

An electron configuration simply lists the shell and subshell labels, with a right superscript giving the number of electrons in that subshell.

In chemistry and atomic physics, an electron shell may be thought of as an orbit that electrons follow around an atom's nucleus.

In 1913, Niels Bohr proposed a model of the atom, giving the arrangement of electrons in their sequential orbits. At that time, Bohr allowed the capacity of the inner orbit of the atom to … 展开
Each subshell is constrained to hold 4ℓ + 2 electrons at most, namely:
• Each s subshell holds at most 2 electrons 展开The list below gives the elements arranged by increasing atomic number and shows the number of electrons per shell. At a glance, the subsets of the list show obvious patterns. In particular, every set of five elements ( electric blue) before each 展开
Each shell is composed of one or more subshells, which are themselves composed of atomic orbitals. For example, the first (K) shell has one … 展开
Although it is sometimes stated that all the electrons in a shell have the same energy, this is an approximation. However, the electrons in one subshell do have exactly the same level of energy, with later subshells having more energy per electron than earlier ones. This … 展开
