dec 26, 1766 - John Dalton
Description:
He had some basic principles about atoms.1) All matter is made of atoms. 2) Atoms are indivisible and indestructible. 3) Compounds are formed by a combination of two or more different kinds of atoms.
Dalton's experiments on gases led to his discovery that the total pressure of a mixture of gases amounted to the sum of the partial pressures that each individual gas exerted while occupying the same space. In 1803 this scientific principle officially came to be known as Dalton's Law of Partial Pressures.
