Plutonium 239 94 Pudecays through a series of a and 8 particles to the thorium isotope...
plutonium-239 (239/94 Pu) is an isotope that can be used as a fuel in nuclear reactors. when the plutonium nucleus is hit by a nuetron it undergoes fission, and splits into two smaller nuclei. there are many possibilities for what the smaller nuclei might be, but we'll just look at one possible fission reaction where it splits into cerium 148 (148/58 Ce) and krypton 89 (89/36 Kr) a) write an equation for the fission of plutonium 239 into cerium 148...
