Identify the starting radioisotopes needed to balance each of these nuclear reactions:a.
b.

How does a chain reaction occur in nuclear fission?

How does nuclear fission differ from normal radioactive decay?

In another fission reaction, uranium-235 bombarded with a neutron produces strontium-94, another small nucleus, and three neutrons. Write the balanced nuclear equation for the fission reaction.

Indicate whether each of the following is characteristic of the fission or fusion process, or both:b. The nuclear process occurs in the Sun.

Bismuth-212 attaches readily to monoclonal antibodies and is used in the treatment of various cancers. This bismuth-212 is formed after the parent isotope undergoes a decay series consisting of four α decays and one β decay (the decays could be in any order). What is the parent isotope for this decay series?
