Titanium has four valence electrons. Valence electrons are generally the electrons located in the outermost shell of an atom and can be gained or lost in a reaction. Valence electrons can be determined by looking at the periodic table; because titanium is four columns from the left, it has four valence electrons.

Titanium’s atomic symbol is Ti, and its atomic number is 22. It belongs to the transition metal group and can form compounds at an oxidation state of +4. Titanium’s abbreviated electron configuration is [Ar] 3d2 4s2. This shows which valence electrons can be lost in a bond with other elements. Examples of compounds include titanium oxide (TiO2), titanium tetrachloride (TiCl4) and rutile (TiO2).
