Notes de l'éditeur
- He was looking for a systematic way to present the chemical elements to his students. He relies on physical properties and atomic weights and predict the existence of new elements. Sometimes I wonder if the fact that he was working for his students and not for the scientific community didn’t allow him to be more bold and audacious allowing his creativity to manifest.
- Moseley could have been awarded the Nobel Prize in Physics, had he not died at age 27 in the service of British Army. Rutherford's paper appeared, Antonius van den Broek first formally suggested that the central charge and number of electrons in an atom was exactly equal to its place in the periodic table (also known as element number, atomic number, and symbolized Z). This proved eventually to be the case.The experimental situation improved dramatically after research by Henry Moseley in 1913.[3] Moseley, after discussions with Bohr who was at the same lab (and who had used Van den Broek's hypothesis in his Bohr model of the atom), decided to test Van den Broek and Bohr's hypothesis directly, by seeing if spectral lines emitted from excited atoms fit the Bohr theory's demand that the frequency of the spectral lines be proportional to a measure of the square of Z.
