No two elements may have the same atomic number. But two elements may have same atomic mass. Hence atomic number is better than atomic mass.
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.

isobars are elements with same mass numbers (Atomic Mass) and different atomic number (number of proton or electron)

They used atomic number instead of Atomic Mass to organize the elements
Mendeleev arranged elements in order of increasing mass. Later modern periodic table was discovered that contains elements arranged by atomic number.
The element symbol represents one mole of element , atomic number represents number of protons, atomic mass represents sum of protons and neutrons.
