- Protactinium is first identified by Kasimir Fajans and O. H. Göhring.
- Henry Moseley shows that nuclear charge is the real basis for numbering the elements and discovers a systematic relation between wavelength and atomic number by using x-ray spectra obtained by diffraction in crystals. Frederick Soddy proposes that isotopes may have differing atomic weights.
- J. J. Thomson shows that charged subatomic particles can be separated by their mass-to-charge ratio, the technique known as mass spectrometry.

Famous quotes containing the word chemistry:
“...some sort of false logic has crept into our schools, for the people whom I have seen doing housework or cooking know nothing of botany or chemistry, and the people who know botany and chemistry do not cook or sweep. The conclusion seems to be, if one knows chemistry she must not cook or do housework.”
—Ellen Henrietta Swallow Richards (1842–1911)
“For me chemistry represented an indefinite cloud of future potentialities which enveloped my life to come in black volutes torn by fiery flashes, like those which had hidden Mount Sinai. Like Moses, from that cloud I expected my law, the principle of order in me, around me, and in the world.... I would watch the buds swell in spring, the mica glint in the granite, my own hands, and I would say to myself: “I will understand this, too, I will understand everything.””
—Primo Levi (1919–1987)
