Writing and Balancing Nuclear Equations
A nuclear equation is a symbolic representation of a nuclear reaction using certain symbols. It is studied in nuclear chemistry and nuclear physics.
Question

In a nuclear reactor, the excess neutrons produced from fission are absorbed by elements, preferably in solid form, which will not undergo fission when they absorb a neutron.

From the table below, choose the best material to absorb neutrons in a nuclear reactor, and then explain your choice.
