He drew on the ideas of the Ancient Greeks in describing atoms as small, hard spheres that are indivisible, and that atoms of a given element are identical to each other.

WebAround 1800 John Dalton performed a series of experiments to measure the ratios of the masses of elements in different compounds. From the results of these experiments, he hypothesized that matter consists of atoms and in 1808 he described the Atomic Theory of Matter in his book A New System of Chemical Philosophy, Part I.

During a chemical reaction atoms are either joined, separated or rearragned. They are never changed into atoms of a different element.
WebDalton proposed that every single atom of an element, such as gold, is the same as every other atom of that element. He also noted that the atoms of one element differ from the atoms of all other elements. Today, we still know this to be mostly true.
