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.
Description: This book explained Dalton's theory of atoms and its applications to chemistry. Importance: The book was one of the first to describe a modern atomic theory, a theory that lies at the basis of modern chemistry. [3]: 251 It is the first to introduce a table of atomic and molecular weights.
Porter Chemical Company was an American toy manufacturer that developed and produced chemistry sets aimed as educational toys for aspiring junior scientists. The company's Chemcraft kits were first sold at major retail by Woodward & Lothrop, and appeared soon after at other retailers in the country.
