Let's go back in time to see how the Atomic Structure developed .
Firstly, the Electrons, found by J.J. Thomson in 1897 via. The Cathode Ray Experiment in which a Cathode and Anode was placed on both ends, that created a beam of electrons
Second, the Protons, found by Ernest Rutherford in 1910. The Gold Foil Experiment, predicted that some particles will pass through and some will deflect because of the positive charge in the nucleus.
Third, the Neutrons, found by James Chadwick in 1932. James Chadwick conducted an experiment wherein he used alpha particles and passed it through the element Beryllium, after which the alpha particles has no charge.
Lastly, The Periodic Table of Elements, found by Dmitri Mendeleev in 1869. It is composed of 118 elements, ordered by the Atomic Number(number of protons).
And that is how the Atomic Structure was developed. Thanks you for watching!
