The dalton (symbol: Da), or unified atomic mass unit (symbol: u), is a unit of mass defined as 1 12 of the mass of an unbound neutral atom of carbon-12 in its nuclear and electronic ground state and at rest. [1][2][3] It is a non-SI unit accepted for use with SI. The word "unified" emphasizes that the definition was jointly accepted by physics (IUPAP) and chemistry (IUPAC ...
John Dalton, English meteorologist and chemist, a pioneer in the development of modern atomic theory. His theory was notable for, among other things, positing that each element had its own kind of atom and that atoms of various elements vary in size and mass. Learn more about Dalton in this article.

The theory of atomism, proposed by Dalton in the early 19th century and derived from meteorological studies, is the foundation for our modern concept of the atom.
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. He thus laid a firm foundation for the development of modern chemistry, and he is widely regarded as one of the giants of science.
