Control rods in nuclear reactors are commonly made of boron and cadmium because these two elements have the ability to

• absorb neutrons

• emit neutrons

• decrease the speed of neutrons

• increase the speed of neutrons

The operation of a commercial nuclear reactor requires an isotope that will undergo

• fission and a controlled chain reaction

• fission and an uncontrolled chain reaction

• fusion and a controlled chain reaction

• fusion and an uncontrolled chain reaction
