1. A beam of protons and a beam of neutrons of the same energy are both harmful to living tissue. The beam of neutrons, however, is less harmful. Suggest why.

2. Germanium, Ge (number 32), computer chips operate faster than silicon, Si (number 14), computer chips. So, how might a gallium, Ga (number 31), chip compare with a germanium chip?
