Q. Describe Subatomic Particles and the Nuclear Atom?
One of the most significant results of Dalton's theory was that it generally persuaded scientists that atoms exist. As a result scientists start research to discover the exact nature of the atom.
Finding of electrons Experiments around the turn of the twentieth century provided evidence that the atom consists of smaller particles. When J. J. Thomson applied a high voltage to two electrodes sealed in an evacuated tube an invisible beam or ray was found to emanate from the negative electrode (cathode) of the tube and travel toward the positive electrode (anode). The path of the ray could be made visible by the glow it caused when it passed across a plate coated with fluorescent material. The beam called a cathode ray could be deflected by electric and magnetic fields.
