The molecules that react to form a compound or any product is called reactants and the thing we get after the chemical reaction is product. Another definition is that the molecules or compounds that are present on the left side of the chemical equation is reactants and the molecules or compounds on the right side are products.

Modern atomic theory is, of course, a little more involved than Dalton's theory but the essence of Dalton's theory remains valid. Today we know that atoms can be destroyed via nuclear reactions but not by chemical reactions. Also, there are different kinds of atoms (differing by their masses) within an element that are known as "isotopes", but isotopes of an element have the same chemical properties.
Many heretofore unexplained chemical phenomena were quickly explained by Dalton with his theory. Dalton's theory quickly became the theoretical foundation in chemistry.
