• Protactinium is first identified by Oswald Helmuth Göhring and Kasimir Fajans.
• 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.^[5] Frederick Soddy proposes that isotopes (a term suggested by Margaret Todd which he introduces) may have differing atomic weights^[6] while he and Fajams independently propose the radioactive displacement law of Fajans and Soddy.^[7]
• J. J. Thomson shows that charged subatomic particles can be separated by their mass-to-charge ratio, the technique known as mass spectrometry.^[8]
• The Bergius process was first developed and patented by German chemist Friedrich Bergius in 1913.

Climatology

• Charles Fabry and Henri Buisson discover the ozone layer.
