Flerovium (Fl)
Element 114 · post-transition metal · group 14, period 7
Flerovium is element 114, a post-transition metal in group 14 and period 7. Its electron configuration is [Rn] 5f14 6d10 7s2 7p2. That leaves 4 valence electrons in the outer shell, with the shells filling 2, 8, 18, 32, 32, 18, 4. Its outer shell is already full, so it does not normally form ions at all.

Flerovium Lewis dot structure
Flerovium has 4 valence electrons, so its Lewis symbol carries 4 dots: four single dots. The dots go one to a side before any of them pair up, so the unpaired ones show exactly how many bonds the atom tends to form.

Electron configuration of flerovium
Orbitals fill from the lowest energy upward. Writing that out for flerovium gives 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 4f14 5s2 5p6 5d10 5f14 6s2 6p6 6d10 7s2 7p2, which is 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 4f14 5s2 5p6 5d10 5f14 6s2 6p6 6d10 7s2 7p2 in plain text.
Everything up to Rn is the same as in that noble gas, so it is usually abbreviated to [Rn] 5f14 6d10 7s2 7p2. The part outside the bracket is what does the chemistry.

Flerovium ion charge
Flerovium has no known ions. It is made a few atoms at a time and decays within seconds, so its chemistry has barely been measured. Its position in group 14 suggests how it might behave, but a charge extrapolated from the group would be a guess, not a measurement.
Common questions
What is the Lewis dot structure of flerovium?
The symbol Fl with 4 dots, one for each valence electron: four single dots. Dots go one to a side before any pair up, the same way electrons fill separate orbitals before sharing one.
How many valence electrons does flerovium have?
Flerovium has 4 valence electrons. For a main-group element the count is the group number minus 10, and flerovium is in group 14.
What is the electron configuration of flerovium?
1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 4f14 5s2 5p6 5d10 5f14 6s2 6p6 6d10 7s2 7p2, or [Rn] 5f14 6d10 7s2 7p2 written from the previous noble gas. Orbitals fill lowest energy first.
How many protons, electrons and neutrons does flerovium have?
A neutral flerovium atom has 114 protons and 114 electrons. Its standard atomic weight is 289, so the most common isotope has about 175 neutrons.
