We now know that atoms do exist, and that some particles smaller than atoms also exist. These subatomic particles are divided into two main groups, the leptons and the hadrons. The best known lepton ("light" particle) is the electron.

There are more subatomic particles besides the electron, proton and neutron, but those are the ones that atoms are composed of. The different elements have different numbers of protons in their nuclei. Hydrogen has one proton, halium has 2, lithium 3, and so on.

Basics about atoms, including structure and behavior. ... Atoms are composed of three type of particles: protons, neutrons, and electron. Protons and neutrons are responsible for most of the atomic mass e.g in a 150 person 149 lbs, 15 oz are protons and neutrons while only 1 oz.

Subatomic particles can be measured once an atom is split. Learn about some of the different types of subatomic particles. ... When physicists first began using accelerators in the 1950s and1960s, they discovered hundreds of particles smaller than the three well-known subatomic particles -- protons, neutrons and electrons.

Subatomic particles are particles that are smaller than an atom. In 1940, the number of subatomic particles known to science could be counted on the fingers of one hand: protons, neutrons, electrons, neutrinos, and positrons.
