A heavy atom like fermium-256 undergoes spontaneous fission about 97 percent of the time when it decays, and in the process, it becomes two atoms. For example, one fermium-256 atom may become a xenon-140 and a palladium-112 atom, and in the process it will eject four neutrons (known ...
Suppose you take a really heavy atom—a stable kind of uranium called uranium-235. Each of its atoms has a nucleus with 92 protons and 143 neutrons. Fire a neutron at uranium-235 and you turn it into uranium-236: an unstable version of the same atom (a radioactive isotope of uranium)...
An atom actually splits instead of throwing off an alpha or beta particle in spontaneous fission — the word "fission" means "splitting." A heavy atom like fermium-256 undergoes spontaneous fission about 97 percent of the time when it decays, and in the process, it becomes two atoms. For...
b. A heavy atom is split. c. It can be controlled easily. d. An electron is lost by the atom. Which of the following statements is true about both nuclear fusion and nuclear fission? a. They occur in the sun. b. Heavy atoms are split. c. Two light nuclei combine. d. Some mass...
Neutron-heavy U-238 has a role to play in the atomic bomb as well since its neutron-heavy atoms can deflect stray neutrons, preventing an accidental chain reaction in a uranium bomb and keeping neutrons contained in a plutonium bomb. U-238 can also be "saturated" to produce plutonium (Pu...

Similar to non-ionizing radiation, ionizing radiation is energy in the form of particles or waves. However, ionizing radiation is so high in energy it can break chemical bonds -- meaning it can charge (or ionize) an atom that interacts with it. At a lower energy, it may strip off a co...
