define atomic mass and atomic number
fnazneen2d:
Atomic mass - the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
Atomic number - the number of protons in the nucleus of an atom, which is characteristic of a chemical element and determines its place in the periodic table.

atomic mass:-the mass of an atom;which is equal to number of protons and neutrons in the atom .
atomic number:-number of protons in the nucleus of atom
example :- atomic number of hydrogen :- 1
➡ number of protons is equal to 1
➡atomic mass is 1.008
atomic number:-number of protons in the nucleus of atom
example :- atomic number of hydrogen :- 1
➡ number of protons is equal to 1
➡atomic mass is 1.008
hmm good answer
