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 flerovium
Flerovium (Fl) has 114 electrons, spread over 7 shells. The diagram places them on circles around the nucleus, from the K shell — the closest — outward.
| Shell | Electrons |
|---|---|
| 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) | 4 |
The Bohr model is a teaching picture: electrons do not travel in circular orbits, but the number of electrons per shell is exact.
