Who Invented Particles

At the end of the 19th century, J.J. Thomson discovered the first fundamental particle: the electron. The discovery of the electron marked the beginning of particle physics.

Who discovered particles?

The first subatomic particle to be identified was the electron, in 1898. Ten years later, Ernest Rutherford discovered that atoms have a very dense nucleus, which contains protons. In 1932, James Chadwick discovered the neutron, another particle located within the nucleus.

Who discovered tiny particles?

For almost 100 years after this, most scientists thought of atoms as solid structures, until in 1897 J.J. Thompson discovered that atoms contained even smaller particles called electrons.
