4 days ago · In this paper we restrict our attention to two of the leading contributors, Joseph J. Thomson (1856–1940) and Ernest Rutherford (1871–1937). We begin with Thomson who sought to describe a structure of the atom that accommodates both its mechanical and electromagnetic properties, but he had little experimental data to base it on.

2 days ago · In 1897, J. J. Thomson discovered that cathode rays are not a form of light but made of negatively-charged particles because they can be deflected by electric and magnetic fields. He measured these particles to be at least a thousand times lighter than hydrogen (the lightest atom).
