When the stated mass number of an element is not a whole number that doesnotmean that there are parts of protons or neutrons present in the atom. It means that that mass number has been calculated to take into consideration theproportions of the different isotopes of that element believed to...
because it has 92 protons and 146 neutrons in a nucleus. Nuclear radioisotopes like uranium-235 are unstable, however, with 92 protons and 143 neutrons, so they very slowly decay, with a half-life of 700 million years. Forcing uranium-235 to decay at a faster rate by neutron bombardment ...
