Free electron configuration tool for all 118 elements. See full configuration, noble gas shorthand, orbital diagrams with up/down arrows, and valence electrons.. Orbital diagrams are pictorial representations of the electron configuration, showing the individual orbitals and the pairing arrangement of electrons. We start with a single hydrogen atom (atomic number 1), which consists of one proton and one electron.

Electron atomic and molecular orbitals A Bohr diagram of lithium In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. [1] For example, the electron configuration of the neon atom is 1s2 2s2 2p6, meaning that the 1s, 2s, and 2p subshells are occupied by two, two.
