Titanium has 22 protons, 26 neutrons and 22 electrons. Titanium is a transition metal with an atomic number of 22 and the atomic symbol of Ti. Its atomic weight is 47.867.
Titanium's 22 protons and 26 neutrons are located in its nucleus. Four energy levels surround the nucleus: its 22 electrons are located here. Two electrons are located in titanium's first energy level and 8 are located in its second energy level. The most number of neutrons, 10, can be found in the third energy level. Titanium's last energy level has two electrons. These electrons are known as valence electrons because they are the ones that are lost or shared during a chemical bond with another atom.
Titanium was first discovered by William Gregor in 1791 and was first produced in pure form by Matthew A. Hunter in 1910. At room temperature, it is a light, solid metal. One unique feature of titanium is that it is the only element capable of burning in an atmosphere that only contains nitrogen.
Titanium has several important uses. Its inability to react in the human body makes it a desirable material in the manufacture of artificial hips, bone pins and spinal rods. It is used in airplanes, rockets and missiles because of its strength and light weight. Titanium also does not corrode in seawater, making it an important material in boat production.
