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.

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. |
