Periodic table and periodic law

WebThe modern periodic table is based on Moseley's Periodic Law (atomic numbers). Moseley determined the number of positive charges in the nucleus by measuring the wavelength of X–rays given off by certain metals in 1913. The wavelengths of the X–ray emissions of the elements coincided with the ordering of the elements by atomic number.
