Developed the idea of electron shells
A useful guide when understanding electron shells in atoms is to note that each row on the conventional periodic table of elements represents an electron shell. Each shell can contain only a fixed number of electrons: the first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, … See more 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 … See more Each shell is composed of one or more subshells, which are themselves composed of atomic orbitals. For example, the first (K) shell … 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 … See more • Periodic table (electron configurations) • Electron counting • 18-electron rule • Core charge 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, and "in the scheme given below the … 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 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 particular, every set of five elements (in electric blue) before each See more WebThe following diagram of the Bohr model shows the electron existing in a finite number of allowed orbits or shells around the nucleus. ...

Electron configuration was first conceived under the Bohr model of the atom, and it is still common to speak of shells and subshells despite the advances in understanding of the quantum-mechanical nature of electrons. An electron shell is the set of allowed states that share the same principal quantum number, n (the number before the letter in the orbital label), that electrons may occupy. An atom's nth electron …
