Atomic number is the number of protons in the nuclei of the atoms of an element. Each element has a unique atomic number. Mass number is the number of protons and neutrons in the nuclei of the atoms of a specific isotope of an element.

What is the general relationship between atomic number and atomic mass weight?

As atomic number rises so does the atomic mass. There is no close relationship. Atomic number is the number of protons in the nucleus. Average atomic mass takes the mass of naturally occurrring isotopes which include the mass of the varying numbers of neutrons present which account for a large proportion of the overall mass of an atom.

How did Henry Moseley revise mendeleevs periodic table?

In 1914 Henry Moseley found a relationship between an element's X-ray wavelength and its atomic number (Z), and therefore rearranged the table by nuclear charge / atomic number rather than atomic weight. Before this discovery, atomic numbers were just sequential numbers based on an element's atomic weight. Moseley's discovery showed that atomic numbers had an experimentally measurable basis.
