Michael Faraday, discovered that atoms had an electrical component.
Finally after experimenting with a crooks and a cathode tubes i can finally demonsrate a negative charge in the cathode tubes
Thomson realized that the accepted model of an atom did not account for negatively or positively charged particles.
AHA, after bombarding a thin gold sheet with alpha particles I have come to the conclusion that all the energy was concentrated into one area.
because of Rutherford's discovery it allowed Neils bhor to create the first theoretical representation of the atom.
In 1932, Chadwick made a fundamental discovery in the domain of nuclear science: he proved the existence of neutrons.
hmm, so after I bombarded Beryllium with alpha particles from the natural radioactive decay of Polonium. The radiation showed high penetration through a lead shield
