Ernest Rutherford

Ernest Rutherford, 1st Baron Rutherford of Nelson  OM PC FRS (30 August 1871 – 19 October 1937) was a New Zealand-born British scientist. He won the Nobel Prize in Chemistry in 1908 for his work on nuclear physics, and for his theory of the structure of the atom.

 Career 
Rutherford was one of the first researchers in nuclear physics, after the discovery of radiation by the French physicist Henri Becquerel in 1896. Rutherford discovered the radioactive half-life, and the three parts of radiation which he named Alpha, Beta, and Gamma. He also discovered that alpha particles were the nuclei of Helium. Rutherford's Geiger–Marsden experiment led to what we know today about the atomic structure, where the atom is a nucleus and electrons orbit around it.

In 1919, Rutherford made the world's first artificial nuclear reaction, where he put alpha particles with nitrogen gas and created particles of oxygen isotopes and protons. This was nuclear transmutation, changing nitrogen gas into oxygen gas.

Rutherford was the leader of the Cavendish Laboratory in Cambridge. He proved the existence of the nucleus and that is was composed of protons and neutrons. In 1932 James Chadwick made an experiment at the Cavendish Lab that showed Rutherford was right.

Rutherford College, a school in Auckland, New Zealand, was named after him.
