Transition metals are extremely useful metals on account of their physical or chemical properties. Transition metal complexes find their application in catalysis, material synthesis, photochemistry, therapy, and diagnostics. Mercury is the only metal with a known melting point (−38.83 °C) lower than caesium. The elements are called "transition" metals because the English chemistry Charles Bury used the term in 1921 to describe the transition series of elements, which referred to the transition from an inner electron layer with a stable group of 8 electrons to one with 18 electrons or the transition from 18 electrons to 32.
