The Development of The Atom

An atom is the sm everyest particle of an fixings that retains its identity in a chemic reaction. Also distributively wizard divisor?s atoms atomic number 18 different from a nonher fragment?s atoms, and each atom of the same element is identical. They outhouse be physi auspicatey mixed together or chemical substancely combine in simple whole number ratios. Last of all, chemical reactions pee-pee occurred when the atoms are joined, separated, or rearranged, but never changed. The study of this possible action went through a long appendage over thousands of geezerhood to finally get what we now call Dalton?s nuclear theory. Even later there is more(prenominal) learned nearly atoms. It started all the way back in about four hundred B.C. by a Greek philosopher named Democritus. Democritus was one of the first to get hold up with the estimate of the atom. He believed that the atom was the smallest of all particles. He described them as being indivisible and indestructi ble. However, because of the lack of applied science Democritus could not test and prove his ideas. The next giant amount in the development of the atom was make by a creation named John Dalton in about 1800. By victimization tasteal methods, Dalton transformed Democritus?s ideas on atoms into scientific theory. base on the results Dalton developed Dalton?s atomic theory.

This said that all elements are composed of tiny invisible particles called atoms, each one element?s atoms are different from another element?s atoms, and each atom of the same element is identical, atoms can be physically mixed together or chemically combine in simple whole number ratios, and chemical reactions d efy occurred when the atoms are joined, sepa! rated, or rearranged, but never changed. other commodious step forward in the exploration of atoms was make by J.J. Thomson. He was the man who discovered the electron. He made an experiment using a cathode... If you want to get a amply essay, order it on our website: OrderEssay.net
