Divisible by chemical or nuclear means
WebThe nucleus of an atom is made up of nucleons i.e. neutrons and protons together. Neutrons are neutral particles, whereas protons are positively charged. Electrons are negatively … WebThe nuclear reaction can be written as: 12 25 Mg + 2 4 He 1 1 H + Z A X. where A is the mass number and Z is the atomic number of the new nuclide, X. Because the sum of the mass numbers of the reactants must equal the sum of the mass numbers of the products: 25 + 4 = A + 1, or A = 28. Similarly, the charges must balance, so:
