Answer» Answer: Alpha particles (a) are COMPOSITE particles CONSISTING of two protons and two neutrons tightly bound TOGETHER (Figure 1). They are emitted from the nucleus of some radionuclides during a form of radioactive decay, called alpha-decay. An alpha-particle is identical to the nucleus of a NORMAL (atomic mass FOUR) helium atom i.e. a doubly ionised helium atom. |
