John Dalton (1766 – 1844): John Dalton was an English chemist. His ideas form the atomic theory of matter. Here are his ideas. All elements are composed (made up) of atoms. It is impossible to divide or destroy an atom. All atoms of the same elements are alike. (One atom of oxygen is like another atom.

Page 1 Atomic Theory About 440 B.C. Empedocles stated that all matter was composed of four "elements" earth, air, water, and fire. Democritus (460-370 BC) Theorized that all matter is composed of small indivisible particles called atomos (“not to cut”, meaning indivisible). Ideas rejected by Greek thinkers of that time

At the top of his diagram, Dalton assigns atom 1 to be hydrogen, 2 nitrogen, 3 carbon, 4 oxygen, 5 phosphorus, etc. He then shows how molecules might look when the atoms combine to form compounds.

Similar to these views, in 1803 John Dalton took the atomic weight of hydrogen, the lightest element, as unity, and determined, for example, that the ratio for nitrous anhydride was 2 to 3 which gives the formula N 2 O 3.Dalton incorrectly imagined that atoms "hooked" together to form molecules. Later, in 1808, Dalton published his famous diagram of combined "atoms":

In the very early 19th Century, the English chemist and physicist John Dalton. Later, in 1913, Rutherford's model of the atom was fleshed out and refined by the.

JOHN NEWLANDS (1837–1898) John Newlands compared elements to musical notes with his law of octaves. As on a scale, every eighth element would share.

Joseph John Thomson a British physicist was born in Cheetham Hill, Manchester on December 18, 1856. He was a man who had enrolled in the prestigious school of Cambridge and he remained a member of the College for the rest of his life, becoming Lecturer of experimental physics.

An atom is the smallest constituent unit of ordinary matter that has the properties of a chemical element.Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small; typical sizes are around 100 picometers (a ten-billionth of a meter, in the short scale). Atoms are small enough that attempting to predict their behavior using classical physics – as.
