Before 1900 only the electron was known.
The proton was discovered by Ernest Rutherford in 1917-1919.
Discovered key information about subatomic particles.
Radium was discovered in 1898 !
Particles in the atom: Neutron: James Chadwick, 1932 Electron: J. J. Thomson, 1897 Proton: Ernest Rutherford, 1919
in late 1800s and early 1900s the industrial revolution took place
Three subatomic particles were discovered in the 1900s: the neutron in 1932, the positron in 1932, and the neutrino in 1956.
Subatomic particles are particles that are smaller than atoms. There are two different types of subatomic particles: elementary particles and composite particles. The first subatomic particle that was discovered was the electron. It was first theorized to exist by G. Johnstone Stoney in 1874 and was confirmed to exist in 1897 by J.J. Thomson.

If you think to particles in the atom: the neutron was discovered in 1932 by James Chadwick.
The neutron was discovered in 1932 by James Chadwick.
The proton was discovered by Ernest Rutherford in 1917-1919.
Ernest Rutherford and James Chadwick were the scientists who discovered the subatomic particles that make up the nucleus. Rutherford discovered the positively charged protons, while Chadwick discovered the uncharged neutrons.

The concept of subatomic particles emerged in the late 19th and early 20th centuries through the research of scientists such as J.J. Thomson, Ernest Rutherford, and Niels Bohr. The discovery of specific subatomic particles like the electron, proton, and neutron can be attributed to a combination of experimental observations and theoretical advancements by multiple scientists over time.
Atoms were found to be divisible after all . But scientists discovered that the atoms were made of smller perticles , called subatomic particles.
