Physical Properties

  • color is gray/ blue
  • very hard
  • highly conductive of heat and electricity
  • melting point of 3017 °C
  • exists in two crystalline phases, alpha and beta (alpha- ductile and soft, beta- hard and brittle)

Chemical Properties

  • one of the most nonreactive metals
  • highly corrosion resistance due to the formation of an oxide film
  • only reacts with fluorine in room temperature
  • is more reactive at higher temperature
  • one of the five major refractory metals


At room temperature it reacts with fluorine gas and some fluorine compounds. It also dissolves in hydrofluoric acid.

Electron Configuration


Fun Facts

  • Was discovered by Anders Gustaf Ekeberg in 1802
  • has the fourth highest melting point of any metallic element
  • Primary use is to make capacitors (like batteries)
  • used in military weapons systems, aircraft, space vehicles, communication systems, computers, and medical applications
  • its believed that its found in the Earth's crust between one and two parts per million
