Og, 118, oganesson : 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 10 4p 6 5s 2 4d 10 5p 6 6s 2 4f 14 5d 10 6p 6 7s 2 5f 14 6d 10 7p 6. Note that these electron configurations are given for neutral atoms in the gas phase, which are not the same as the electron configurations for the same atoms in chemical environments.
[124] 2022 calculations expect the electron affinity of oganesson to be 0.080(6) eV. [8] Monte Carlo simulations of oganesson's molecular dynamics predict it has a melting point of 325 ± 15 K and a boiling point of 450 ± 10 K due to relativistic effects (if these effects are ignored, oganesson would melt at ≈ 220 K).
The symbol [Og] indicates the probable electron configuration of oganesson (Z = 118), which is currently the last known element. The configurations of the elements in this table are written starting with [Og] because oganesson is expected to be the last prior element with a closed-shell (inert gas) configuration, 1s 2 2s 2 2p 6 3s 2 3p 6 3d 10 ...

The electron configuration of the element Og, or Oganesson. Items portrayed in this file depicts. ... oganesson: 11:50, 23 October 2012: 2,000 × 2,000 (12 KB) DePiep:
The noble gases have full valence electron shells. Valence electrons are the outermost electrons of an atom and are normally the only electrons that participate in chemical bonding. Atoms with full valence electron shells are extremely stable and therefore do not tend to form chemical bonds and have little tendency to gain or lose electrons. [35]
For a given configuration, the order of writing the orbitals is not completely fixed since only the orbital occupancies have physical significance. For example, the electron configuration of the titanium ground state can be written as either [Ar] 4s 2 3d 2 or [Ar] 3d 2 4s 2.
