What is the charge of… the uranium nucleus? Alpha particles, also called alpha rays or alpha radiation, consist of two protons and two neutrons bound together into a particle identical to a helium-4 nucleus.They are generally produced in the process of alpha decay, but may also be produced in other ways.Alpha particles are named after the first letter in the Greek alphabet, α.The symbol for the alpha particle is α or α 2+. The effective nuclear charge on an electron is given by the following equation: Z eff = Z – S. where Z is the number of protons in the nucleus (atomic number), and S is the number of electrons between the nucleus and the electron in question (the number of nonvalence electrons).
