WebMoseley's Contribution To Our Understanding of The Atom. Before Moseley and his law, atomic numbers had been thought of as a semi-arbitrary ordering number, vaguely increasing with atomic weight but not strictly defined by it. Moseley's discovery showed that atomic numbers were not arbitrarily assigned, but rather, they have a strong … WebIn other words, he discovered that an element’s atomic number is identical to how many protons it has.
