Answer» Why was the BASIS of classification of elements changed from the atomic mass to the atomic number? The PROPERTIES of elements depend upon the number of electrons present in the valence shell which are related to atomic number. Thus the properties of different elements can be COMPARED if we know their atomic numbers.Explanation:this is the correct answer hope U like it plss MARK as brainliest
