(a) What is the composition of α, β and γ radiations? (b) Can a hydrogen () nucleus emit an alpha particle? (c) Which one α, β and γ radiation has the least penetrating power?

Question

KnowledgeBoat · Accepted Answer

(a) α radiation consists of two protons and two neutrons. β radiation is composed of fast moving electrons emitted from the nucleus of an atom while γ radiation is photon or electromagnetic waves like X-rays and light. (b) No, hydrogen () nucleus cannot emit an alpha particle because an alpha particle consists of two protons and two neutrons whereas hydrogen () nucleus does not have two protons and two neutrons. (c) α radiations have least penetrating power.
