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.
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.
The subatomic particle with a negative charge is the electron.
Electrons are the subatomic particles that have a negative charge.
The particle you are referring to is an "electron." It is a negatively charged subatomic particle found in atoms.
The electron is the subatomic particle located farthest from the nucleus of the atom.
