Lawrencium has 103 electrons and protons. Home. The number of neutrons is different for each of the 12 isotopes of Lr. Note that, each element may contain more isotopes, therefore this resulting atomic mass is … Possible oxidation states are +3. 103: Atomic Number: Lr: Element Symbol: Lawrencium: Element Name: 262: Average Atomic Mass: The atomic weight is basically a measurement of the total number of particles in an atom 's nucleus including both protons and neutrons. It is a solid metal at room temperature and it has a melting point of 1627°c predicted, the boiling point is unknown. It is named in honor of Ernest Lawrence, inventor of the cyclotron, a device that was used to discover many artificial radioactive elements. Latimer at the University of California, Berkeley, by bombarding a mixture of the … Lawrencium is a synthetic chemical element with chemical symbol Lr (formerly Lw) and atomic number 103.
