Predicted propertiesMany physical properties of this element are theoretical calculated values, not experimental measurements. Transactinides (Z ≥ 104) are only synthesized as a few atoms with very short half-lives. Source: IUPAC 2021.

Bohr model of moscovium

Bohr model of moscovium (Mc): 115 electrons in 7 shells — 2, 8, 18, 32, 32, 18, 5

Moscovium (Mc) has 115 electrons, spread over 7 shells. The diagram places them on circles around the nucleus, from the K shell — the closest — outward.

ShellElectrons
K (n = 1)2
L (n = 2)8
M (n = 3)18
N (n = 4)32
O (n = 5)32
P (n = 6)18
Q (n = 7)5

The Bohr model is a teaching picture: electrons do not travel in circular orbits, but the number of electrons per shell is exact.
