How Did Isaac Newton Contribute To The Creation Of Atomic Theory

Good Essays

Many different scientists contributed to the atomic theory known today. Every single one of them played an important role in creating the atomic theory known today. Around 400 BCE Leucippus, the scientist who originally came up with the atomic theory, began to lay a foundation for the theory known today. Then, Democritus adopted the ideas of Leucippus , his mentor. Democritus soon developed the idea of an atom. Democritus believed everything was made up tiny particles of matter, he called these particles atoms. He chose this name because, in Greek, atom means indivisible. After Democritus, Isaac Newton was the next scientist to contribute to the atomic theory. Isaac Newton began to realize that atoms were constantly moving and were not …show more content…

This idea came from the findings of Democritus. His second conclusion was that all atoms of one type have the same mass and properties. Along with this point, Dalton understood atoms of different types had different masses and properties. Dalton’s fourth point consisted of the fact that chemical reactions do not create, change, or destroy elements, they are only rearranged in these reactions. The final point of Dalton’s theory was when different elements combine, they do so in some ratio of whole numbers. John Dalton was able to find mass numbers for twenty one different elements. The Law of Mass Conservation, created by Antoine Lavoisier, was supporting evidence to Dalton’s atomic theory. Next, J. J. Thompson contributed ideas to the existing theory. In 1898 he used a cathode ray and discharge tube to aid in the discovery of electrons. The electron has an antimatter counterpart. This counterpart is known as the positron, positrons have the same mass as electrons. J.J. Thompson was able to determine the existence of a + particle . He also founded the plum pudding model , this model showed negative particles scattered around a positive …show more content…

His work helped to contribute to the modern understanding of the atomic theory. Thus, at the points A B C and D the electron would be subjected to maximum repulsive and attractive forces while the positions a b and c would be stable But once disturbed from one of the latter positions the electron would oscillate for a while and finally shift over into a new position of equilibrium At the distance OE the curve representing the force exerted on the electron would become practically the same as that corresponding to Coulomb's law Such a law of force might thus explain radiation phenomena and perhaps the raison d etre of the constant h in the quantum theory. In 1905 Albert Einstein was the next scientist to contribute to the atomic theory findings. His work on the theory of relativity became the basis of nuclear energy. In 1909 came the following important discovery, the discovery of the nucleus. Ernest Rutherford started to form an idea of the structure of an atom. Rutherford used the scattering of alpha particles when shot through gold foil to discover the structure of an atom, he called this experiment the gold foil experiment. Rutherford also decided to call Thompson’s + particles protons. P+ is another symbol that means
