Nonelectrolyte a substance whose water solution does not conduct an electric current appreciably.
Non-metal one of a class of elements which are usually poor conductors of heat and electricity and are electronegative.
Nonpolar Covalent Bond a bond in which there is essentially equal attraction for the shared electrons and a resulting balanced distribution of charge.
Normal Solution a solutions containing one gram equivalent of solute per liter of sloution.
Normality the concentration of a solution expressed in gram-equivalents of solute per liter of solution.
