Flerovium (Fl): Bohr Model, Protons, Neutrons & Electrons
Flerovium is element number 114, a superheavy in group 14, period 7. Its atom has 114 protons, 175 neutrons and 114 electrons arranged in 7 shells: 2, 8, 18, 32, 32, 18, 4.

Protons, neutrons and electrons in flerovium
Le atomic number of flerovium is 114, so every flerovium atom has 114 protons. A neutral atom has the same number of electrons, 114. The number of neutrons depends on the isotope: neutrons = mass number − atomic number. For flerovium-289, that is 289 − 114 = 175 neutrons. Every isotope of flerovium is radioactive; 289 is the mass number of its most stable one.
How to draw the Bohr model of flerovium
- Draw the nucleus and write 114 p⁺ et 175 n⁰ inside it.
- Draw the first shell and put 2 electrons on it (the first shell holds at most 2).
- Draw the second shell and put 8 electrons on it.
- Draw the third shell and put 18 electrons on it.
- Draw the fourth shell and put 32 electrons on it.
- Draw the fifth shell and put 32 electrons on it.
- Draw the sixth shell and put 18 electrons on it.
- Draw the seventh shell and put 4 electrons on it.
- Check: 2 + 8 + 18 + 32 + 32 + 18 + 4 = 114 electrons, the same as the number of protons.
From potassium onwards the shells don’t simply fill as 2, 8, 8: the fourth shell starts before the third is full, so the real arrangement above (2, 8, 18, 32, 32, 18, 4) is the one to draw.
Electron configuration
The electron configuration of flerovium is [Rn] 7s² 5f¹⁴ 6d¹⁰ 7p². Its 4 outer electrons decide how it reacts: it usually shares electrons in covalent bonds.
