Valency of Flerovium (Fl)
The valency of Flerovium is 4 — it has 4 valence electrons, and it shares all four to complete its outer shell.
Looking for Flerovium's valency without wading through a whole chapter? Here is the direct answer first, then the tables and derivations examiners want to see.

Counting the valence electrons
From the configuration [Rn] 5f^14 6d^10 7s^2 7p^2, Flerovium's outermost shell carries 4 electrons. These are the electrons shown as dots in electron-dot diagrams — the hands Flerovium uses to hold other atoms.
Position check: Flerovium belongs to group 14 of the periodic table, period 7. For main-group elements in groups 13–18, a quick rule is valency = group number − 10, which gives 4 here.
Valency vs valence electrons
Valence electrons are what you count (4 for Flerovium); valency is what the atom will do to complete its outer shell (4 here). Keep the two words straight and half the periodic-table chapter writes itself.
Students also ask
How do I find the valency of Flerovium from its group?
Flerovium sits in group 14; groups 13–17 follow valency = group − 10, giving 4 (though Flerovium also shows 4).
Why does Flerovium show a fixed valency?
Flerovium has 4 valence electrons and reaches a complete outer shell in one consistent way, so its valency stays fixed at 4.
