What Is A Relative Atomic Number?

I think that was wrong. Relative Atomic Mass is the Atomic Mass (not Number) which is based on the average of the AM's of all the isotopes of an atom considering their proportions found in nature. I don't see a need for a term Relative Atom Number since that value excludes neutrons and hence is lower and hence would be a whole number, no averaging was needed.

Is this clear?

It is the number of fatties in the solar system (america has the most)
