Question

what is the valency of titanium

Answer 1

There are 26 known isotopes of titanium ranging from Ti-38 to Ti-63. ... melting point of 1660 +/- 10°C, boiling point of 3287°C, specific gravity of 4.54, with a valence of 2, 3, or 4.

Answer 2

We can check valency for a bonded or non-bonded atom. It indicates the bonding capacity of any element in the given compound. It can be easily checked with the charges on respective ions.

But for an atom, we need to check the number of valence electrons that can be shared by atom to form compound or molecule.

Titanium is a d-block element, present in 3d series with atomic number 22. The valence shell configuration is $3 d^{2}, \ 4 s^{2}$.

Since, there are 2 electrons in the valence shell, the valency of the titanium will be 2.
