Livermorium (Lv): Bohr Model, Protons, Neutrons & Electrons
Livermorium is element number 116, a superheavy in group 16, period 7. Its atom has 116 protons, 177 neutrons and 116 electrons arranged in 7 shells: 2, 8, 18, 32, 32, 18, 6.

Protons, neutrons and electrons in livermorium
Le atomic number of livermorium is 116, so every livermorium atom has 116 protons. A neutral atom has the same number of electrons, 116. The number of neutrons depends on the isotope: neutrons = mass number − atomic number. For livermorium-293, that is 293 − 116 = 177 neutrons. Every isotope of livermorium is radioactive; 293 is the mass number of its most stable one.
How to draw the Bohr model of livermorium
- Draw the nucleus and write 116 p⁺ et 177 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 6 electrons on it.
- Check: 2 + 8 + 18 + 32 + 32 + 18 + 6 = 116 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, 6) is the one to draw.
Electron configuration
The electron configuration of livermorium is [Rn] 7s² 5f¹⁴ 6d¹⁰ 7p⁴. Its 6 outer electrons decide how it reacts: it usually shares electrons in covalent bonds.
