The nucleus of the hydrogen atom was found to be a proton ( p +). In 1907, Ernest Rutherford performed an experiment (the gold foil experiment) that showed that the atom is mainly empty space, and that almost all its mass is concentrated in the tiny atomic nucleus.

Later, it was realized that the electron has wave-like properties as well as particle-like properties, and this understanding led to the concept of "wave-particle duality" of elementary particles. The existence of this particle was demonstrated in 1897, by J. Johnstone Stoney to postulate the existence of a subatomic particle, the electron (denoted e −), in 1874. In particular, experiments in electrochemistry led G.

Those ideas began to be shattered when, around the turn of the twentieth century, experimental evidence suggested that each atom is composed of smaller particles. Showing two protons (red), two neutrons (green), and two electrons (yellow).Įarly ideas about atoms portrayed them as the indivisible, fundamental building blocks of matter. By combining these basic components, an essentially unlimited number of composite particles can be assembled. Bosons, on the other hand, may be thought of as "pixels of force"-particles associated with fundamental forces. It may be helpful to think of fermions as "pixels of matter"-fundamental particles normally associated with matter. The elementary particles fall into one of two classes: Fermions and bosons. Researchers in particle physics and nuclear physics study these various particles and their interactions. Rather, they are produced in cosmic rays and during scattering processes in particle accelerators. Most of them, however, are not encountered under normal conditions on Earth. An electron is an example of an elementary particle protons and neutrons are examples of composite particles.ĭozens of subatomic particles have been discovered. It may be either an elementary (or fundamental) particle, or a composite particle, also called a hadron. A subatomic particle is a particle smaller than an atom.
