In chemistry and atomic physics, an electron shell may be thought of as an orbit followed by electrons 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 farther and farther from the … See more In 1913 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 increase to eight electrons as the atoms got larger, … See more Each subshell is constrained to hold 4ℓ + 2 electrons at most, namely: • Each s subshell holds at most 2 electrons • Each p subshell holds at most 6 electrons • Each d subshell holds at most 10 electrons See more 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 … See more Each shell is composed of one or more subshells, which are themselves composed of atomic orbitals. For example, the first (K) shell has … See more 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. … See more • Periodic table (electron configurations) • Electron counting • 18-electron rule • Core charge See more WebAn electron shell, or main energy level, is the part of an atom where electrons are found orbiting the atom's nucleus.
