How many isotopes does gallium have
WebIsotopes are nuclides that have the same atomic number and are therefore the same element, but differ in the number of neutrons. Mass numbers of typical isotopes of Gallium are 69; 71. Atomic Mass of Gallium Atomic mass of Gallium is 69.723 u. The atomic mass is the mass of an atom. WebCalifornium was first made in 1950 at Berkeley, California, by a team consisting of Stanley Thompson, Kenneth Street Jr., Albert Ghiorso, and Glenn Seaborg. They made it by firing helium nuclei (alpha particles) at curium-242. The process yielded the isotope californium-245 which has a half-life of 44 minutes.
