This philosophy has found its most successful application in natural science: according to the atomistic view, the material universe is composed of minute particles, which are considered to be relatively simple and immutable and too small to be visible. It is a hard, brittle, bluish-white transition metal in the platinum group that is found as a trace element in alloys, mostly in platinum ores. Although the concept of the atom dates back to the ideas of Democritus, the English meteorologist and chemist John Dalton formulated the first modern description of it as the fundamental building block of chemical structures.

Early atomic theory stated that the characteristics of an object are determined by the shape of its atoms. Little progress was made in atomic theory until the 19th century, when a number of experiments were done and their results could be explained by atomic theory. (Use example calculations to determine average atomic mass of atoms from relative abundance and actual isotopic mass to develop understanding). Democritus 460-371 B.C. ! His atomic theory said that elements consist of small particles called atoms; Said that atoms combine in simple whole number ratios to form molecules of compounds; Dalton was able to determine the relative masses of the atoms J.J.

C4.10B Recognize that an element always contains the same number of protons. Dalton’s atomic theory also explains the law of constant composition: if all the atoms of an element are alike in mass and if atoms unite in fixed numerical ratios, the percent composition of a compound must have a unique value without regards to the sample analyzed. Click and drag (or swipe) or use the arrows to scroll the timeline.
