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...

Uranium-235 is a rare isotope of uranium that can be used for power plants as well as bombs. Its nucleus decays to a thorium-231 nucleus by emitting an α-particle. Uranium has atomic number 92, and thorium has atomic number 90. A nuclear reaction such as this is written using the following notation: 235U → 231Th + α Mass number is the number of protons plus the number of neutrons. It is the top number in this notation. In these nuclear...
