What is the quantum theory of an atom? How is the cloud model different from Bohr model? Who discovered the nucleus of an atom? What is Ernest Rutherford famous for in nuclear chemistry? Which atomic model was proposed as a result of J. J. Thomson's work?
J.J. Thomson is the scientist who discovered the electron. At the time of his discovery, he was working in the Cavendish Laboratory at Cambridge University in England. Prior to his discovery, scientists believed the atom was the smallest unit of matter. Thomson proved the existence of ...
ThreatManager算一个,ReaperService算一个,Absolution算半个,rDns算半个,再加上operational oncall duty,这个已经不是加不加油的问题,而是加不加铀的问题。 也许一年前加入了Windows Azure现在会过的更好,but you never know,另一个平行世界中的我现在如何,无法知道。重要的是,现在的工作很好,学到很多又有更多新...
The electron was the first subatomic particle discovered in 1896. U.K. Physicist JJ Thomson made the discovery while he was conducting an experiment with cathode rays. After determining the electron’s mass and charge, it was determined that they make up 0.06% of an atom’s mass. The electr...
