Answer 1

atomic number decides the property of any metal and atomic mass is defined as the mass of an atom

Answer 2

Answer:

An atomic number is the number of protons in the center (of a cell or atom) of an atom, which decides/figures out the chemical properties of an element and its place in the periodic table. Atomic weight is another term for atomic mass.

Explanation:

Atomic mass is the mass of an atom of a chemical element expressed in atomic mass units. It is about equal to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative (oversupplies/large amounts) of different isotopes.
