Dear deebur1998@gmail.com
Thanks for asking us a question in Ask the Expert section of TopperLearning.com.
In case of multiple questions within a query, please post each question individually and let us know where you are getting stuck so that we would be able to explain things better.
Solution of your first query,
An isolated particle can only decay into particles which are less massive than the original particle. The rest mass energy of the original particle E=mc2 is converted into the masses of the decay products and also into their kinetic energies. The decay must conserve energy, linear momentum, angular momentum, electric charge, lepton number, and baryon number. The tritium nucleus, or triton, is unstable simply because it is more massive than its decay products which are a helium-3 nucleus, an electron, and an electron anti-neutrino. This is called beta decay because an electron ejected from the nucleus was named a beta particle by early researchers. Symbolically,where the superscripts label the "atomic mass" A which is the number of nucleons (proton and neutrons), while the subscripts label the "atomic number" Z which is the charge in units such the proton charge is +1.
