Valency of Moscovium (Mc)
The valency of Moscovium is 3 — it has 5 valence electrons, and it loses them to complete its outer shell.

Counting the valence electrons
From the configuration [Rn] 5f^14 6d^10 7s^2 7p^3, Moscovium's outermost shell carries 5 electrons. These are the electrons shown as dots in electron-dot diagrams — the hands Moscovium uses to hold other atoms.
Position check: Moscovium belongs to group 15 of the periodic table, period 7. For main-group elements in groups 13–18, a quick rule is valency = group number − 10, which gives 5 here.
Valency vs valence electrons
Valence electrons are what you count (5 for Moscovium); valency is what the atom will do to complete its outer shell (3 here). Keep the two words straight and half the periodic-table chapter writes itself.
Students also ask
How do I find the valency of Moscovium from its group?
Moscovium sits in group 15; groups 13–17 follow valency = group − 10, giving 5 (though Moscovium also shows 3).
Why does Moscovium show a fixed valency?
Moscovium has 5 valence electrons and reaches a complete outer shell in one consistent way, so its valency stays fixed at 3.
