Answer 2

Answer:

Atomic number is the total number of protons present in the nucleus of an atom.

Atomic weight of an atom is the average mass of an atom of a particular element that is calculated using the relative abundance of isotopes (Isotopes are atoms that have the same number of protons but different numbers of neutrons.).

The main difference between atomic number and atomic weight is that atomic number gives the number of protons present in the nucleus whereas atomic weight gives the mass of an atom.
