Electrons can also easily be diverted using magnets, and, based on this fact, their mass was computed to be almost zero. The discovery of electrons showed that these subatomic particles can traverse a vacuum without any conducting materials, like metal wires or air. In 1897, Thomson discovered that the atoms of metals, like tungsten, that he sealed inside a vacuum tube emit negatively-charged particles when an electric current is applied to them. This became popularly known as the plum pudding model. Thomson, proposed an improved model of the atom that was based on his experiments with cathode ray tubes. In 1904, Sir Joseph John Thomson, known as J.J. Thomson discovered the first subatomic particle: the electron. The most notable was his assertion that atoms were indivisible. Though revolutionary for its time, there were a few issues with Dalton’s atomic theory.
He won the 1933 Nobel prize in physics with colleague Paul Adrien Maurice Dirac "for the discovery of new productive forms of atomic theory". Schrödinger proposed an original interpretation of the physical meaning of the wave function.
