Addition Reaction
A reaction in which two atoms or groups of atoms are added to a molecule, one on each side of a double or triple bond. Types of addition reaction include electrophilic, nucleophilic (polar) and free radical addition (non-polar).
Nuclear Reactor
A system in which controlled nuclear fisson reactions generate heat energy on a large scale, which is subsequently converted into electrical energy.
Endothermic
Describes processes that absorb heat energy.
Particulate Matter
Fine divided solid particles suspended in polluted air.
Formula Unit
The smallest repeating unit of a substance. The molecule for nonionic substances
Half-Life
The time required for half of a reactant to be converted into product(s). The time required for half of a given sample to undergo radioactive decay.
Octahedral
A term used to describe molecules and polyatomic ions that have one atom in the center and six atoms at the corners of a octahedron.
Ionization Energy
The minimum amount of energy required to remove the most loosely held electron of an isolated gaseous atom or ion.
Radioactive Tracer
A small amount of radioisotope replacing a nonradioactive isotope of the element in a compound whose path (for example, in the body) or whose decomposition products are to be monitored by detection of radioctivity, also called a radioactive label.
Cis-
The prefix used to indicate that groups are located on the same side of a bon about which rotation is restricted.
