Valency of Meitnerium (Mt)
The valency of Meitnerium is 2 — it has 2 valence electrons, and it loses them to complete its outer shell.

Counting the valence electrons
From the configuration [Rn] 5f^14 6d^7 7s^2, Meitnerium's outermost shell carries 2 electrons. For a d-block element the nearby inner "d" subshell can also lend electrons, which is where variable valency comes from.
Position check: Meitnerium belongs to group 9 of the periodic table, period 7.
Valency vs valence electrons
Valence electrons are what you count (2 for Meitnerium); valency is what the atom will do to complete its outer shell (2 here). Keep the two words straight and half the periodic-table chapter writes itself.
Students also ask
How do I find the valency of Meitnerium from its group?
Meitnerium sits in group 9; for this transition group the safe exam answer is its common valency, 2.
Why does Meitnerium show a fixed valency?
Meitnerium has 2 valence electrons and reaches a complete outer shell in one consistent way, so its valency stays fixed at 2.
