16: Alpha particles are a common form of nuclear radiation. Which statement most accurately
describes alpha particles?
A Alpha particles are relatively massive, positively charged particles composed of 2 neutrons
and 2 protons. They have the weakest penetrating power.
B Alpha particles are relatively massive, negatively charged particles composed of 2 neutrons
and 2 electrons. They have the weakest penetrating power.
C Alpha particles are single, high-energy electrons, possessing a negative charge and a
moderate amount of penetrating power.
D Alpha particles are neutral and are composed of pure energy and therefore have no mass.
They are the most dangerous form of radiation.
