It is a lustrous transition metal with a silver color, low density, and high strength. Titanium is resistant to corrosion in sea water, aqua region, and chlorine. ... In its unalloyed condition, titanium is as strong as some steels, but less dense.

As is characteristic of transition elements, titanium has a variable valence and occurs commonly in the bi-, tri-, and tetra-valent states.
· Gases. The chemical reactivity of titanium is dependent upon temperature. The metal’s action with other substances proceeds more readily at elevated temperatures. This property is especially exemplified by the metal’s extreme reactivity to the gases of the atmosphere at high temperatures.
· The metal combines with oxygen to form a long series of oxides from TiO to Ti7O12, each of which exhibits a different hue and, at short time exposures, a rainbow-colored surface film is produced.
·The reactivity of titanium with nitrogen is similar to its action with oxygen where a yellow-brown scale is formed on the surface as the nitride. Nitrogen will diffuse into the lattice with a restricted depth of penetration. This property has been employed in the nitride casing of the metal.
