The continuous release of nuclear energy caused when on fission reaction triggers more nuclear reactions is a _

Answer is: nuclear chain reaction.

For example fission of heavy isotope uranium-238.

The decay chain of ²³⁸U is called the uranium series.

Decay start with U-238 and ends with Pb-206. There are several alpha and beta minus decays.

The half-life for the radioactive decay of U-238 is 4.5 billion years and is independent of initial concentration.

Alpha decay is radioactive decay in which an atomic nucleus emits an alpha particle (helium nucleus) and transforms into an atom with an atomic number that is reduced by two and mass number that is reduced by four.

In beta minus decay atomic number Z is increased by one, neutron is converted to a proton and an electron and an electron antineutrino.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
