ResourceOn This Day - Oct 31 : Robert Mulliken died
He was awarded the 1966 Nobel Prize in Chemistry for his work on chemical bonds and describing the electronic structure of molecules using the molecular orbital method. His research still leads this field.

ResourceOn This Day - Apr 30 : Discovery of the electron
Thomson was studying the properties of cathode rays, and found that they were over 1,000 times lighter than the hydrogen (H) atom and that they were the same mass irrespective of the parent atom. He called these particles “corpuscules”, but scientists later dubbed them “electrons”.

ResourceOn This Day - Feb 29 : Bohr issued bowl of balls
Danish physicist Niels Henrik David Bohr made fundamental contributions to the understanding of atomic structure and quantum mechanics, for which he received the Nobel Prize in Physics in 1922.

ResourceOn This Day - Apr 25 : Wolfgang Pauli was born
He is most famous for the Pauli “exclusion principle”, which states that in an atom no two electrons can occupy the same quantum state simultaneously. He was awarded the Nobel Prize in Physics in 1945 for his work.

ResourceOn This Day – Jul 24 : Sir James Chadwick died
He received the Nobel Prize in Physics 1935 for his discovery of the neutron, a subatomic particle with zero electrical charge. Neutrons are found in the nucleus of all elements (except hydrogen) along with protons, which carry a positive charge.
