Question

Match the following:Part A1. This is a process of one nucleus decaying to two or more smaller nuclei. 2. This is the period of time it takes for a radioactive sample to decay to half of its original amount. 3. Atoms of the same element with varying number of neutrons. 4. Positively-charged particles consisting of two protons and two neutrons emitted by radioactive materials. 5. Electrons emitted by the nucleus when a neutron is changed to a proton during radioactive decay. 6. This is a high energy photon resulting from the redistribution of the charge within the nucleus. 7. The process in which nuclei with small masses are combined to form a nucleus with a larger mass. 8. Power, especially electricity, the source of which is fission or fusion. 9. Byproducts of radioactive decay. 10. The energy stored in bonds within the nucleus of an atom; energy released from a fission or fusion reaction. 11. The spontaneous emission of energy and/or matter from the nucleus of an unstable atom. As a result of this emission, the atom may be converted into an atom of a different element.Part Ba. nuclear powerb. radioactivityc. half lifed. fusione. isotopesf. beta particleg. nuclear energyh. fissioni. nuclear wastej. alpha particlek. gamma radiation
