Question

why the atomic number is considered more important than atomic mass of the elements​

Answer 1

Answer:

The mass number is the total of protons and neutrons in the nucleus. ... For example carbon -12 has atomic number of 6 and mass number 12. Nitrogen -12 has an atomic number 7 but mass number 12. Thus atomic mass does give exact information of an element, hence atomic number is more important than mass number.
