# What is the Lewis dot diagram for titanium?

Titanium lies in Group 4 of the Periodic Table and has 4 valence electrons. But we would seldom write a Lewis dot structure for titanium metal. $T i C {l}_{4}$ is a common titanium compound (and is used for skywriting by light aircraft, why?), but so is solid $T i C {l}_{3}$; $T i C {l}_{2}$ is also known.
