Dalton atomic theory

Answer 1

John Dalton 

6 September 1766 – 27 July 1844) was an English chemist, physicist, andmeteorologist. He is best known for introducing the atomic theory into chemistry, and for his research intocolour blindness, sometimes referred to as Daltonism in his honour.

Atomic Theory. ... In an article he wrote for the Manchester Literary and Philosophical Society in 1803, Daltoncreated the first chart of atomic weights. Seeking to expand on his theory, he readdressed the subject of atomic weight in his book A New System of Chemical Philosophy, published 1808

Although two centuries old, Dalton's atomic theory remains valid in modern chemical thought. 1) All matter is made of atoms. Atoms are indivisible and indestructible. 3) Compounds are formed by a combination of two or more different kinds of atoms.

Dalton's atomic theory. (ˈdɔːltənz) n.

Compounds are formed by combination of atoms in simple ratios to give compound atoms(molecules).
