WebIt starts with Neptunium-237 and ends in the stable nucleus Bismuth-209. Neptunium is called a transuranic element because it lies beyond uranium in the periodic table. Uranium has the highest atomic number (Z = 92) (Z = 92) of any element found in nature. Elements with Z > 92 Z > 92 can be produced only in the laboratory. They most probably ...
WebWe know that the atomic number of bismuth is 83 and the atomic average mass number is about 209. Neutron = 209 – 83 = 126. Therefore, a bismuth atom has one hundred twenty-six neutrons.
