How did henry moseley rearrange the elements
WebChemists have always looked for ways out arranging the elements to reflect to similarities between my properties. The modern periodic table lists the elements in book of increasing atomic number (the numerical for protons in the nuclear off an atom). Historically, not, relative atomic masses were use by scientists trying to organise the elements. WebWhen Moseley arranged the elements in the periodic table by their number of protons rather than their atomic weights, the flaws in the periodic table that had been making scientists …

Moseley ‘s contribution to the science of physics was the justification from physical laws of the previous empirical and chemical concept of the atomic number. This stemmed from his development of Moseley’s law in X-ray spectra.
WebMoseley's experiments in X-ray spectroscopy showed directly from their physics that cobalt and nickel have the different atomic numbers, 27 and 28, and that they are placed in the Periodic Table correctly by Moseley's objective measurements of their atomic numbers.
