Atomic Theory

EARLY ATOMIC THEORIES 1. Democritus - describe members as little naughtily balls or invisible little compact sphere nuclear number 18 in motion continually in empty space. He named these particles atoms, the indivisibles. 2. Empedocles- affirmed that there are tetrad fundamental unchangeable instalments: earth, fire, water and station. These elements unify temporarily to class matter. 3. Aristotle- was wizard of the more believers of the four - element. He added that the elements change from one from to the other by adding or removing heat and moisture.

Thales believed that water is the primal element; Anaximenes believed that air is the basal element; Heraclitus believed that fire is the primary element. In 1803, potty Dalton concluded that the properties of matter could be explained in terms of atoms. Daltons atomic theory of mat ter was found on the adjacent postulates: 1. All matter is made up of extremely small, long-lasting or indivisible particles called atom. 5. All atoms of a given element are identical, but they differ from those of each other element. 6. The atom is the smallest part of an element that can translate part in a chemic reaction. 7.

Atoms combine in ratios of small only numbers to form different chemic compounds. ( lawfulness of Definite Proportion) 8. Atoms are neither created nor destroyed in any chemical reaction. ( lawfulness of double Proportion) The Law of Conservation of sm okestack states that in a chemical reaction,! the total mass of the reactant is equalise to the total mass of the products. The Law of Definite/Constant organization states that: A given chemical compound always go for the same proportion by mass of its constituent elements. The Law of Multiple Proportions states that: When two elements combine to form two or more different compounds, if the fall of one element is constant, the pile of the other...If you want to get a full essay, order it on our website: OrderCustomPaper.com
