Bromine is a chemical element with atomic number 35 which means there are 35 protons and 35 electrons in the atomic structure. This name had been used in books of the Soviet Bloc as the official name of the element. Because of its closed-shell electron configuration, its density and melting and boiling points differ significantly from those of most other lanthanides. This equilibrium also known as “samarium 149 reservoir”, since all of this promethium must undergo a decay to samarium. The chemical symbol for Hydrogen is H.
