electroneutral, a.|ɪˌlɛktrəʊˈnjuːtrəl|
[f. electro- + neutral a.]
Electrically neutral; having no net electrical charge.
1961in Webster. 1970Nature 19 Dec. 1233/2 These derivatives of the electroneutral molecule, NH, have at last come into their own. 1974Ibid. 3 May 15/2 A 12-6-1 potential, which combines the Lennard–Jones 6-12 potential with partial charges attributed to the participating atoms while keeping the bond electroneutral. 1982Biochim. & Biophys. Acta DCLXXXVIII. 797/1 The fact that ions are transported by electroneutral processes does not preclude their ability to interact electrostatically with the transmembrane surface.
So eˌlectroneuˈtrality n., the condition of being electroneutral.
[1948L. Pauling in Jrnl. Chem. Soc. 1461, I have..formulated the postulate of the essential electrical neutrality of atoms: namely, that the electronic structure of substances is such as to cause each atom to have essentially zero resultant electrical charge..and these resultant charges are possessed mainly by the most electropositive and electronegative atoms, and are distributed in such a way as to correspond to electrostatic stability.] 1951J. O'M. Bockris tr. Kortüm's Textbk. Electrochem. I. iv. 158 Owing to the principle of electroneutrality, only the net activity of an electrolyte can be subjected to direct measurement. 1984Greenwood & Earnshaw Chem. of Elements (1986) vi. 184 Electroneutrality can then be achieved by adding the appropriate number of protons. |
