diatom en · NOUN · etymology 2

Pronunciation

  • /daɪˈæ.təm/ (Received-Pronunciation)
  • /daɪˈæ.təm/ (General-American)

Etymology

From di- + atom.

Meanings

  1. A molecule composed of two atoms of the same element; a homonuclear diatomic molecule.
    • We show here, through a systematic study of the covalent chemical bond covering the entire periodic system, that the maximum bond multiplicity is six. The maximum value is reached by the tungsten diatom, W₂. No other pair of atoms in the periodic system (atomic numbers smaller than about 100) reaches a higher bond order. 2007, Björn O. Roos, Antonio C. Borin, Laura Gagliardi, “Reaching the Maximum Multiplicity of the Covalent Chemical Bond”, in Angewandte Chemie, volume 46, number 9, →DOI, archived from the original on 27 Apr 2024, pages 1469–1472:
