Which best describes a chain reaction associated with a nuclear reaction? Neutrons released during a fusion reaction cause other
nuclei to fuse. Neutrons released during a fission reaction cause other nuclei to split. Helium nuclei released during a fission reaction cause other nuclei to split. Helium nuclei released during a fusion reaction cause other nuclei to fuse.
The statement that describes a chain reaction brought about by a nuclear reaction is "neutrons <span>released during a fission reaction cause other nuclei to split." This is applicable to fission reactions only wherein atoms split and produce neutrons that also cause further atoms to split, thus creating a chain or series of reactions.</span>
An element is composed of a single type of cell. So we can expect only one kind of element. For example if it is a carbon element it will contain only carbon atoms.
