These traits describe either a chemical or a nuclear reaction. which statements describe a nuclear reaction? check all that apply.  involves the loss, gain, or sharing of electronsmay involve a change in total massinvolve relatively low energy changesoccur outside the nucleusinvolve very high-energy changesinvolve changes in nuclides when decay occurs

The answers that apply;

There are two types of radioactive reactions; fission and fusion. Fission involves the splitting of an unstable isotope (with a high mass number) into stable elements (of lower mass number) that differ in characteristics from the parent atoms. Fusion involves the fusion of two light atoms into a heavier atom. Both reactions emit huge quantities of energy in the process.

atomic = no of protons.

mass number-atomic number = neutron number
