Question

what is the relation between atomic number and atomic weight?

Answer 1

hey.....
here is yours answer.....
Atomic mass (ma) is the mass of an atom. A single atom has a set number of protons and neutrons, so the mass is unequivocal (won't change) and is the sum of the number of protons and neutronsin the atom. ... Atomic weight is a weighted average of the mass of all the atoms of an element, based on the abundance of isotopes.
