An image from John Dalton's A New System of Chemical Philosophy, the first modern explanation of atomic theory.. This timeline of chemistry lists important works, discoveries, ideas, inventions, and experiments that significantly changed humanity's understanding of the modern science known as chemistry, defined as the scientific study of the composition of matter and of its interactions.
Alchemy in the medieval Islamic world refers to both traditional alchemy and early practical chemistry (the early chemical investigation of nature in general) by Muslim scholars in the medieval Islamic world. The word alchemy was derived from the Arabic word كيمياء or kīmiyāʾ[1][2] and may ultimately derive from the ancient Egyptian ...
Robert Boyle FRS [2] (/ b ɔɪ l /; 25 January 1627 – 31 December 1691) was an Anglo-Irish [3] natural philosopher, chemist, physicist, alchemist and inventor. Boyle is largely regarded today as the first modern chemist, and therefore one of the founders of modern chemistry, and one of the pioneers of modern experimental scientific method.
See also: Etymology of chemistry. The word alchemy comes from old Frenchalquemie, alkimie, used in Medieval Latinas alchymia. This name was itself adopted from the Arabicword al-kīmiyā(الكيمياء). The Arabic al-kīmiyāin turn was a borrowing of the Late Greekterm khēmeía(χημεία), also spelled khumeia(χυμεία) and khēmía ...

The experiments of Antoine Lavoisier (1743–1794), a French chemist regarded as the founder of modern chemistry, were among the first to be truly quantitative. Lavoisier showed that although matter changes its state in a chemical reaction , the quantity of matter is the same at the end as at the beginning of every chemical reaction.
History of molecular theory. Space-filling model of the H 2 O molecule. In chemistry, the history of molecular theory traces the origins of the concept or idea of the existence of strong chemical bonds between two or more atoms. A modern conceptualization of molecules began to develop in the 19th century along with experimental evidence for ...
Atomism (from Greek ἄτομον, atomon, i.e. "uncuttable, indivisible") [ 1 ][ 2 ][ 3 ] is a natural philosophy proposing that the physical universe is composed of fundamental indivisible components known as atoms. References to the concept of atomism and its atoms appeared in both ancient Greek and ancient Indian philosophical traditions.
