Chapter 21 Nuclear Chemistry
a collective name for neutrons and protons
a general term for a specific isotope of an element
The difference in mass between a nucleus and its separate nucleons.
nuclear binding energy
the energy released when a nucleus is formed from nucleons
A reaction that involves a change in the nucleus of an atom
A change in the identity of a nucleus as a result of a change in the number of its protons
unstable radioisotopes decay releasing gamma rays, alpha and beta particles.
A cluster of 2 protons and 2 neutrons emitted from a nucleus in one type of radioactivity
an electron emitted from the nucleus during some kinds of radioactive decay
a very high energy form of electromagnetic radiation, emitted from the nucleus
succession of radioactive decay that ends when a stable isotope is produced
The time required for one half of the atoms of a radioisotope to emit radiation an decay products
The process by which a large nucleus is split into smaller nuclei
Series of fission reactions caused by the release of additional neutrons in every step
The process by which two or more small nuclei fuse to make a bigger nucleus
a cadmium rod used in a nuclear reactor to absorb neutrons from fission reactions
a radiation-absorbing material that is used to decrease radiation leakage from nuclear reactors
Slows down fast neutrons to increase the chance of more reactions. (So they don’t pass through the nuclei)
nuclear power plant
a type of nuclear technology involving the controlled use of nuclear fission to release energy for work including propulsion, heat and the generation of electricity.
