About Titanium

Strong, light, and highly resistant to corrosion, titanium combines load-bearing capacity with low density. It is a silvery transition metal of atomic number 22 and atomic mass 47.867, with a density of 4.51 g/cm³ and a high melting point of 1941 K. Its [Ar] 3d2 4s2 configuration gives an electronegativity of 1.54 and a first ionization energy of 659 kJ/mol. William Gregor recognized the element in 1791. Its strength-to-weight ratio and resistance to corrosion make titanium valuable for aerospace components, medical implants, and sporting equipment. The metal belongs to group 4, period 4.
