Hafnium is a chemical element with symbol Hf and atomic number 72. A lustrous silvery gray tetravalent transition metal hafnium chemically resembles zirconium and is found in zirconium minerals. Its existence was predicted by Dmitri Mendeleev in 1869 though it was not identified until 1923 making it the penultimate stable element to be discovered (rhenium was identified two years later).
