Tantalum

Vanessa Romero

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

Reaction

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

Electron Configuration

1s22s22p63s23p63d104s24p64d105s25p64f145d36s2

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
