Lawrencium is a synthetic element. It is named after Ernest Lawrence, the inventor of the cyclotron, a particle accelerator used to combine radioactive elements. Lawrencium is the final elements of the actinide series and it can only be produced in particle accelerators, it does not exist in nature. Much like Nobelium, Lawrencium’s discovery was claimed by many different groups. Lawrencium’s discovery was credited by IUPAC to the Lawrence Berkelely laboratory in 1971 but in 1992 it awarded joint discovery to the Dubna research group in Russia. It is a solid metal at room temperature and it has a melting point of 1627°c predicted, the boiling point is unknown.
