Solution

Deae student, Atomic weight is the weight of protons and neutrons in the nucleus of the atom while Atomic number is the number of electrons or protons in an atom.Chemical properties are determined by the number of outermost valence electrons as they (electrons)participate in any chemical reaction.whereas the protons and neutrons lie to the centre of the atom and weight only determine the physical properties of atoms and molecules.
