Question

Quizplus · Accepted Answer

Alpha rays are actually alpha particles, which are made up of two protons and two neutrons. They are helium atoms that have been stripped of their electrons, giving them a positive charge. They can also be accompanied by gamma rays, which are a form of electromagnetic radiation. Alpha particles are not de Broglie waves or fast-moving electrons.
