Although a schoolteacher, a meteorologist, and an expert on color blindness, john dalton is best known for his pioneering theory of atomism He also developed methods to calculate atomic weights and structures and formulated the law of partial pressures. From his own experiments and observations, as well as the work of his peers, dalton proposed a new theory of the atom This later became known as dalton's atomic theory
The general tenets of this theory are as follows All matter is composed of extremely small particles called atoms. Dalton is best known for his formulation of the atomic theory, which clarified our understanding of how atoms combine to form compounds, and how atoms may form new combinations during chemical reactions. Chemist john dalton is credited with pioneering modern atomic theory
