Complete the nuclear equation for the following: a) tritium, 3H undergoes β decay. With 28 protons and 20 neutrons 48Ni is "doubly magic" (like 208Pb) and therefore much more stable (with a lower limit of its half-life-time of .5 s) than would be expected from its position in the chart of nuclides. Some of these batteries, called accumulators, are rechargeable, but even they need to be replaced for charging. Since the strong force is much stronger than the electric force at subatomic range, the energy levels in the nucleus are much larger than those for the atom, and this is why the energy released in nuclear reactions is so much greater than the energy released in chemical reactions (eg a nuclear electric power facility produces energy from a lot less fuel than a similarly powerful coal-fired electric power facility). However, chemical cells discharge in a relatively short time, limiting their applications in autonomous devices. 0-1e+? Write a nuclear equation for the beta decay of Th-234.
