Question

Why was atomic number considered a better basis for the classification of the elements then the atomic mass?​

Answer 1

Here's your answer: -

because The atomic mass of the element relates to the nucleus which is present in the centre of the atom. But the properties of the elements depend upon the electronic configuration which is linked with atomic number. Therefore atomic number is a better basis for the classification of the elements than the atomic mass.

Hope it's helps you ✌✌

Answer 2

Answer:

The atomic mass of an elements relates to the nucleus which is present in the centre of the atom. The properties of the elements are linked with the electronic configuration of their atoms. Only the electrons are involved in the bond formation. Since the electrons are linked with atomic number. Therefore, the atomic number is a better basis for the classification of the elements then atomic number.
