Titanium has 22 electrons spread over four different energy levels. There are two electrons in the first level, eight electrons in the second level, 10 electrons in the third level, and 12 electrons in the fourth level.
Titanium is the ninth most common element on Earth; it is found in igneous rocks and sediments. It is hard, lustrous and strong as steel but much less dense. Commercially, it is used as an alloy agent in projects that require great structure strength but low overall weight, such as aircraft and missiles.
Titanium is also a common component of desalinization plants and ship hulls because it does not corrode in the presence of seawater like other metals. Unlike other metals, it connects well with bone and it is used frequently to repair damaged joints and teeth.
