What is the difference of a atomic number and atomic weight?
Atomic number is the number of a chemical element in the periodic table of Mendeleev; it is equal in the neutral state with the number of protons or electrons. Atomic weight is the mass of a chemical element (considering the isotopic composition) expressed in atomic mass units.
Who determined the relationship between atomic weight and weight relations in chemical reactions?
Not sure.
