Dalton's and Rutherford's Advancements to the Atomic Theory
Quite a few scientists have helped to create and extend ideas on what an atom is and what its components are. One of these discoverers, John Dalton, developed the first modern atomic theory. Although much of his theory is still true today, one point was disproved by Ernest Rutherford. Dalton's atomic theory had several parts to it. He believed atoms were indivisible, or impossible to break down into smaller particles. Also, he said elements are all consisted of atoms and that the atoms of each element are different from each other. All of the atoms of the same element are identical, but different from atoms of other elements. According to Dalton's theory, these different elements can be chemically merged or physically mixed to make compounds. Also, when forming chemically combined compounds with chemical reactions, atoms cannot be created or destroyed. Earnest Rutherford preformed en experiment later that proved an idea of Dalton's wrong. With his gold foil experiment, Rutherford found atoms to be consisted of at least two smaller parts, unlike Dalton's idea that atoms are indivisible. He established that an atom includes a tiny, positively charge nucleus, which is surrounded by electrons. Both John Dalton and Ernest Rutherford, among other great researchers and scientists, assisted in creating the atomic theory that exists today. Dalton's theory was the first modern atomic theory, but a part of it was disproven by Rutherford. Rutherford found atoms were not indivisible and that they consist of smaller parts and particles. Even though one of Dalton's ideas was proved wrong, his other thoughts still apply to today's atomic

    The nucleus is one of the most important part of the atom because it contains the two particles protons and neutrons. Rutherford was also the first scientist that made a model that contains all three particles. Some might say that since it wasn't Rutherford that discovered the electron the credit should go to JJ Thomson. Also because Thomson was Rutherford’s teacher. However Thomson could not be the best contributor. He had thought that the atom was one whole sphere with only two of the three particles. Others might say that it might be Niels Bohr and or Erwin Schrodinger. Bohr and Schrodinger both have models and ideas that incorporate all three particles. Their models also possess the nucleus and electrons orbiting it. In addition Bohr and Schrodinger had corrected Rutherford’s model by correcting the electron’s position and where we could potentially find the electron. Despite that Bohr and Schrodinger had only been able to find their discoveries because they had Rutherford’s model as a base. So overall the number one reason Rutherford is the best contributor is because he discovered the nucleus and that everyone else did…

    John Dalton: revived/revised D’s ideas called: Dalton’s Atomic theory which basically states that all matter are composed of extremely tiny atoms, all atoms of a given element are identical (same size, mass, and chemical properties), atoms cannot be created, divided into smaller particles, or destroyed (similar to the Law of Conservation of Mass), different atoms combine in simple whole-number ratios to form compounds (see below), in a chemical reaction, atoms are separated, combined, or rearranged.…

    As far back, from my school years, as I can remember the word atom signified the smallest particle of matter. This is a very layman like attitude a scientist would abhor, because a scientist knows that this concept of ‘the smallest particle of matter ' has been changing rapidly over the years. The Greeks, it is said, coined the word “atom”. When this concept was articulated by the Greeks, there were no electronic equipments or high-tech labs to verify and further explore this “atom”. Technological advances have given today’s physicists the needed methods and means to explore matter in ways never possible in the early days of the atom.…

    John Dalton was an English chemist, physicist, and meteorologist. Dalton was born in 1766. He is best known for his work in color blindness, and of course, his Atomic Theory. His theory gave us an idea about what the universe is really made up of, and he paved the way for many more important scientific discoveries after he died in 1844.…

In 1811, Avogadro published an article in Journal de physique that clearly drew the distinction between the molecule and the atom. He pointed out that Dalton had confused the concepts of atoms and molecules. The "atoms" of nitrogen and oxygen are in reality "molecules" containing…

    As he did these extraneous experiments, John Dalton proposed that every chemical element is made of atoms of a single, yet unique type, which cannot be demolished or transformed. In chemical means they cannot be changed although atoms can be combined to create more intricate structures, which are known as chemical compounds. After all of his research and analysis of the results he then concluded that this was the first scientific theory of the atom.…

    This brilliant experiment is another reason why Rutherford qualifies for this award. Because, from his experiment, he discovered Alpha and Beta rays. “Chem Teacher” states that, “Rutherford devised a way to record the location of the alpha particles by surrounding the bombarded object with a sheet coated in ZnS, which would emit of flash of light when hit with an alpha particle. Through previous experiments of shooting alpha particles, Rutherford knew they had considerable mass and speed. He then hypothesized that these particles would penetrate a thin metal foil, although they may scatter slightly because of the charge in the metal atom's subatomic particles. After shooting alpha particles through the thin sheet of gold, Geiger, Marsden and Rutherford discovered that a small proportion of the molecules were scattered at larger than 90° angles. This caused them to conclude that there was a small fraction of the total volume of the atom that held most of the mass of the atom” (Chem Teacher). His nuclear model then replaced the Plum Pudding model.…
