The … Webfirst ionization energies of the elements German physicist Wilhelm Conrad Röntgen had discovered X-rays in 1895, and Becquerel thought they might be related to fluorescence and phosphorescence, processes in which substances absorb and emit energy as light. Webatomic theory , first stated by John Dalton, an English scientist, in 1808. It consists of three parts: All matter is composed of atoms. Atoms of the same element are the same; atoms of different elements are different. Atoms combine in whole-number ratios to form compounds.
