Atomic Theory

EARLY ATOMIC THEORIES 1. Democritus - mark members as slim disadvantageously balls or invisible little compact sphere nuclear number 18 in motion continually in empty space. He named these split upicles atoms, the indivisibles. 2. Empedocles- confirm that there argon quartet fundamental unchangeable instalments: earth, fire, pee and station. These elements unify temporarily to recoil matter. 3. Aristotle- was unrivaled of the more believers of the foursome - element. He added that the elements change from one from to the other by adding or removing heat and moisture. He alike believed that love is the jam that unites the elements and skirmish is the force that disunites the elements. 4. Thales believed that water is the indigenous element; Anaximenes believed that air is the primary feather(a) element; Heraclitus believed that fire is the primary element. In 1803, potty Dalton reason out that the properties of matter could be explained in terms of atoms. Daltons nuclear theory of matter was establish on the adjacent postulates: 1. on the whole matter is made up of extremely small, long-lasting or indivisible particles called atom. 5. All atoms of a given element argon identical, but they differ from those of every other element. 6. The atom is the smallest part of an element that can conduct part in a chemic reaction. 7.

Atoms deepen in ratios of small only poesy to form different chemic compounds. ( lawfulness of Definite Proportion) 8. Atoms are neither created nor destroyed in any chemic reaction. ( law of nature of divalent Proportion) The honor of Conservation of push-down stack states that in a chemic reaction, the total mass of the reactant is suitable to the total mass of the products. The Law of Definite/Constant theme states that: A given chemical compound always defy 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 betide of one element is constant, the pot of the other...If you want to get a full essay, order it on our website: Orderessay
