New Zealand physicist who classified radiation into alpha, beta, and gamma types and discovered the atomic nucleus. He won the 1908 Nobel Prize in chemistry.
New Zealand-born British physicist who was a pioneer of subatomic physics. He discovered the atomic nucleus and named the proton. Rutherford demonstrated that radioactive elements give off three types of rays, which he named alpha, beta, and gamma, and invented the term half-life to measure the rate of radioactive decay. For this work he was awarded the Nobel Prize for chemistry in 1908.
