The electron was discovered by J.J. Thompson. Simply, he used a Cathode ray tube and magnetic fields to "bent" the flow of particles. He also determined the mass to charge ratio of the electron, thus proving it to be less massive (and a component) of the atom. By extension, as electrons were negative and matter is generally neutral, he knew that there must be something positive inside the atom to balance the charge. He came up with the plumb pudding model of the atom.
The proton was discovered by Ernest Rutherford. He bombarded a sheet of gold foil with alpha particles, and found that the majority of these particles passed through (thus disproving the plumb pudding model) while very few were radically deflected or reflected.
The neutron was discovered by James Chadwick. His experiment was a variation on that used by Irene Curie and her husband involving polonium and alpha radiation.
The discovery of each of the three basic particles that make up the atom is take up by three separate questions - one for each one. All there questions are listed in the related questions area below, and they are links to those questions.
The basic particle of an element is called an atom. Each atom is made up of protons, neutrons, and electrons.
The smallest indivisible particle of an element is an atom. Each atom consists of a nucleus containing protons and neutrons, surrounded by electrons in orbitals.
An atom is the smallest particle in matter with unique chemical properties. Each element is characterized by the number of protons in its nucleus, which determines its chemical behavior.
Yes, a particle can be a single atom.
The smallest particle of matter is an atom, which was discovered in the early 20th century through experiments such as the gold foil experiment by Ernest Rutherford. It was found that atoms are made up of even smaller particles called protons, neutrons, and electrons.

By looking at the atom.
The smallest particle of an element is called an atom.
An atom. An atom can be split into smaller pieces, but if you do that, you no longer have the same element.
The representative particle in plutonium is an atom. Plutonium is a chemical element with the atomic number 94, and each atom of plutonium contains 94 protons in its nucleus.
An atom is the smallest particle in matter with unique chemical properties. Each element is characterized by the number of protons in its nucleus, which determines its chemical behavior.
