Thomson discovered the first subatomic particle, the electron, while researching cathode rays. To explain the neutrality of atoms, Thomson proposed a model of the atom in which negative electrons are scattered throughout a sphere of positive charge. He called his atom the plum pudding model.

WebOn April 30, 1897, British physicist J.J. Thomson announced his discovery that atoms were made up of smaller components. This finding revolutionized the way scientists thought about the atom and had major ramifications for the field of physics. What are the 5 main points of Dalton’s atomic theory? His theory contained five main propositions: WebAtoms are made up of protons, neutrons, and electrons. However, if you remove any of these particles the atom will have different properties. An atom is the smallest particle of an element that has all the properties of the element. For example, sodium in its pure form reacts violently with water. When you take away one of its electrons, it ...
