  1. Democritus. 460 B.C. - 370 B.C. Democritus recognized that if you continued to cut a stone into smaller and smaller, at some point you would reach a piece so tiny it could no longer be divided. Democritus called these infinitesimally small pieces atomos. He theorized that atomos were specific to thing that they come from
  2. B.C.E. Plato said that the atoms that make up everything are made of right triengles. 430. Dalton found the atomic theory of matter, adding to it the idea that different elements had different characteristic atomic weights. Atomic Theory Timeline: Sarah Patterson. Atomic Theory Time Line. Atomic Structure Timeline
  3. Plato introduced the atomic theory in which ideal geometric forms serve as atoms, according to which atoms broke down mathematically into triangles, such that the form elements had the following shape: fire (tetrahedron), air (octahedron), water (icosahedron), earth (cube)
  4. Plato was so impressed with this discovery that he was convinced that atoms of matter must derive from these five fundamental solids. But at the time the Greek periodic table consisted only of earth, water, air and fire (i.e. four atomic types). Therefore, Plato postulated that a fifth atomic type must exist which Aristotle later called `ether'

If you've been in science media for any length of time, there are two arguments you will hear invoked to support almost any questionable position; that Einstein did his best work while he was a patent clerk and that Galileo was oppressed by the Catholic Church. One of those is wrong; Galileo was not actually oppressed. As a slightly overdue commemoration of Albert Einstein's 133 nd birthday, I would like to make a quick note of his most elemental contribution to atomic theory-he was the first person to show a way to prove the existence of atoms-using an ordinary microscope!.

Prize motivation: for the discovery of new productive forms of atomic theory. Prize share: 1/2 Work In Niels Bohr's theory of the atom, electrons absorb and emit radiation of fixed wavelengths when jumping between fixed orbits around a nucleus. The theory provided a good description of the spectrum created by the hydrogen atom, but needed to. Contribution to Atomic Theory. He developed the periodic table. He organized the elements into a table according to their atomic weights. When the elements were arranged in ascending order in their weights, their properties repeated in a pattern. He used the table by a means of predicting new elements as well as just organizing them The first proponents of an atomic theory were the Greek philosophers Leucippus and Democritus who proposed the following model in the fifth century B.C. 1. Matter is composed of atoms separated by empty space through which the atoms move. 2. Atoms are solid, homogeneous, indivisible, and unchangeable.. Schrodinger's Atomic Theory. Defined an orbital of an atom as: The region of space that surrounds a nucleus in which two electrons may randomly move. (which is the Quantum Model of Electrons) Schrodinger said that all matter acts as waves, and electrons themselves were wavelike. He said that electrons were constantly moving and didn't. Democritus. Democritus, known in antiquity as the 'laughing philosopher' because of his emphasis on the value of 'cheerfulness,' was one of the two founders of ancient atomist theory. He elaborated a system originated by his teacher Leucippus into a materialist account of the natural world

Mendeleev is known for his work on the Periodic Law and creation of the first Periodic table. In 1869 he created the first Periodic Table. The Periodic Law states that when elements are arranged according to their atomic number, elements with similar properties will appear at regular intervals. In 1868-1870 he wrote The Principles of Chemistry Albert Einstein (1879-1955) was a German-born theoretical physicist and winner of the 1921 Nobel Prize in Physics. Einstein influenced the beginning of the Manhattan Project. In collaboration with Leo Szilard, Einstein wrote a letter to President Roosevelt in 1939, warning of possible German nuclear weapons research and proposing that the United States begin its own research into atomic energy Wolfgang Pauli. Austrian-born scientist Wolfgang Ernst Pauli made numerous important contributions to twentieth-century theoretical physics, including explaining the Zeeman effect, first postulating the existence of the neutrino, and developing what has come to be known as the Pauli exclusion principle. A cornerstone of the modern understanding. Diagram explaining Plato's Allegory of the Cave #5 He came up with epistemology or theory of knowledge. Plato believed that true knowledge may only be derived from world of ideal and timeless forms.As an example in his Socratic dialogue Meno, a boy is able to find mathematical truths without observation of the world, arriving at the truth by being asked questions and considering the answers

Atomic Theory Boyle is known for his insistence on mechanical explanations for natural phenomena. He rejected Aristotelian theories based on ideas like the four elements (earth, water, fire, and air) Lived 1887 - 1915. Henry Moseley was an outstandingly skilled experimental physicist. In 1913 he used self-built equipment to prove that every element's identity is uniquely determined by the number of protons it has. His discovery revealed the true basis of the periodic table and enabled Moseley to predict confidently the existence of four new [ Atomic Theory Contribution Robert Boyle's major contribution to the atomic theory was that he helped develop a definition of an element ( any substance that can be broken into 2 or more substances is not an element) and helped with the death of the four elements Atomic Orbital (Quantum) Atomic Theory of Matter. Ninety years later, Pierre and Marie Curie were to discover and isolate radium, a new element which spontaneously disintegrated into other elements. This proved that the atoms of one element at least were not indivisible. Marie Curie's Study: The Discovery of Radium and Polonium /Radioactivity

In 1913, Niels Bohr proposed a theory for the hydrogen atom, based on quantum theory that some physical quantities only take discrete values. Electrons move around a nucleus, but only in prescribed orbits, and If electrons jump to a lower-energy orbit, the difference is sent out as radiation. Bohr's model explained why atoms only emit light. What Was Robert Boyle's Contribution to the Atomic Theory? Robert Boyle (1627-1691) is known as The Father of Chemistry for his discovery that atoms must exist based on the relationship between pressure and volume of gas. His theorem called Boyle's Law reasons that because a fixed mass of gas can be compressed, gas must be made of.

Antoine Lavoisier. Law of Conservation of Matter (Antoine Lavoisier) The first breakthrough in the study of chemical reactions resulted from the work of the French chemist Antoine Lavoisier between 1772 and 1794 John Dalton was famous because he was a pioneer in the development of modern atomic theory. Dalton had published a famous essays with the title Meteorological Observations and Essays. Today, Dalton become famous because he is the first pioneer in modern atomic theory. Many people consider him as the Creator of Modern Atom Science Niels Bohr was an accomplished physicist who came up with a revolutionary theory on atomic structures and radiation emission. He won the 1922 Nobel Prize in physics for his ideas and years later. Atomic theory - that is, the belief that all matter is composed of tiny, indivisible elements - has very deep roots. Initially, the theory appeared in thousands of years ago in Greek and. The atomic theory, during that time, gave a peep into the future of modern science that it is now. Interestingly, Democritus used his theory on atoms to explain the way the universe functions. The philosopher believed that humans only created gods to make sense of incomprehensible things around them. The universe, in his view, is a very.

The controbution Aristotle made to the Atomic theory was that He believed in the four elements of air, earth, water and fire; Aristotle felt that regardless of the number of times you cut a form of matter in half, you would always have a smaller. Robert Millikan's primary contribution to atomic theory came as a result of his oil-drop experiment, which measured an electron's charge. Previously, J.J. T had suggested the hypothesis that an electron's mass was at least 1,000 times less than the mass of the tiniest atom Aristotle's theory of matter has been proven wrong. Many more elements have been discovered. One only has to look at the periodic table to see this is the case. The only thing Aristotle discovered that caries on to the modern atomic theory is the fact that there are elements, which is implied in Aristotle's theory Einstein's biggest contribution to the Atomic Theory was that he was able to fully prove through usage of evidence that atoms did indeed exist, and he was also able to demonstrate that electrons could leave metal through usage of light. He also created the mass energy equivalence equation, and this paved the way for the creation of the atomic bomb

Atomic theory has been revised over the years to incorporate the existence of atomic isotopes and the interconversion of mass and energy. In addition, the discovery of subatomic particles has shown that atoms can be divided into smaller parts. However, Dalton's importance in the development of modern atomic theory has been recognized by the. You may take it for granted that matter is made up of atoms, but what we consider common knowledge was unknown until relatively recently in human history.Most science historians credit John Dalton, a British physicist, chemist, and meteorologist, with the development of modern atomic theory Zeitschr, xiv., 1912, p. 39), 'if all elements be arranged in order of increasing atomic weights, the number of each element in that series must be equal to its intra-atomic charge.'
