Valency of Tungsten (W)
The valency of Tungsten is 6 — it has 2 valence electrons, and it gains 2 to complete its outer shell.
Teachers call it "one fact, fully handled" — exactly what this page does for Tungsten. The answer sits at the top in bold; scroll for the working, the shell-by-shell breakdown and the two questions students ask most.

Counting the valence electrons
From the configuration [Xe] 4f^14 5d^4 6s^2, Tungsten'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: Tungsten belongs to group 6 of the periodic table, period 6.
Valency vs valence electrons
Valence electrons are what you count (2 for Tungsten); valency is what the atom will do to complete its outer shell (6 here). Keep the two words straight and half the periodic-table chapter writes itself.
Students also ask
How do I find the valency of Tungsten from its group?
Tungsten sits in group 6; for this transition group the safe exam answer is its common valency, 6.
Why does Tungsten show a fixed valency?
Tungsten has 2 valence electrons and reaches a complete outer shell in one consistent way, so its valency stays fixed at 6.
