WebTimeline Description: Atomic theory is the scientific theory of the nature of matter. The theory states that matter is made up of small particles called atoms. Prior to this theory, matter was thought to be able to be divided into any small quantity. The word atom is derived from the Greek atmos, meaning indivisible. Loading Timeline... WebDec 2, 2024 · Robert Millikan was responsible for designing and fine tuning experiments that confirmed the most important scientific theories of his time, paving the way for the theory of atomic structure. When the electron was dropped from an oil tank, he was able to accurately determine its charge. build a hot tub table

WebThe 19th and early 20th centuries saw great advances in our understanding of the atom. This module takes readers through experiments with cathode ray tubes that led to the discovery of the first subatomic particle: the electron. The module then describes Thomson’s plum pudding model of the atom along with Rutherford’s gold foil experiment that resulted … WebAtomic Theory before and after Millikan’s experiment Before: J.J. Thomson discovered the electron and the fact that the electron was negatively charged. However, the size measurements were believed to be After: Millikan’s discoveries gave evidence that the size of an electron is 1/1837 of the size of hydrogen atom. WebFeb 27, 2013 · Robert Andrew Millikan was an American experimental physicist whom won 1923 Nobel Prize in physic for his experiment with the charged oil-drop. He was the second scientist to expand on the knowledge of the electron charge after J.J Thomson. He was the first scientist who discovered the actual charge and value of a single electron. build a hot tub cover
