Name the three subatomic particles of an atom.
Name the three subatomic particles of an atom.
Step 1 Understanding the concept: Protons, neutrons, and electrons are the three subatomic particles.
Electrical charges exist in two subatomic particles: protons and electrons.
Protons carry a positive charge, whereas electrons carry a negative charge.
Step 2 Explanation of subatomic particles: During, the 1880s and 1890s, scientists looked for the carriers of electrical qualities in materials using cathode rays. Their efforts helped in the 1897 discovery of the electron by English physicist J.J. Thomson.
Eugene Goldstein used a tube full of hydrogen gas (similar to Thomson's tube) to discover positive particles. This had the effect of the positive particle having the same charge as the electron but being charged in the opposite direction. The proton is the term given to the positive particle.
James Chadwick, a scientist, did an experiment in which he attacked Beryllium with fast-moving helium particles (alpha particles) produced by Polonium's natural radioactive disintegration in 1932.
