Question 1920 ptsHarry Moseley's discovered that an element's dominant X-ray spectral lines increase regularly and validates thearrangement and organization of the periodic table. Another implication of this discovery at that time was that there is aconnection betweenO an element's atomic number and its number of protonsO an element's properties and its atomic weightO an element's atomic number and its atomic weightO an element's radioactivity and its number of electronsNext ▸

The correct answer to the question based on Harry Moseley's discovery is "an element's atomic number…
