Titanium is a chemical element with the symbol Ti and atomic number 22. To determine the number of valence electrons in titanium, we can look at its electron configuration. Titanium has an electron configuration of [Ar] 4s2 3d2.
The valence electrons are the electrons in the outermost shell, which in the case of titanium are the two electrons in the 4s subshell and the two electrons in the 3d subshell. Therefore, titanium has a total of 4 valence electrons.
This means titanium can form a variety of compounds, gaining or losing electrons during chemical reactions, which is crucial for its applications in alloys and other chemical compounds.
