ionicity Chem.|aɪəˈnɪsɪtɪ| [f. ionic a.2: see -icity.] Ionic character (in a chemical bond or a crystal).
1946Nature 26 Oct. 592/2 The absence of a similar fall in the C{b1}O bond-breaking energy passing from methyl to ethyl alcohol can be satisfactorily explained in terms of the increased ionicity of the C{b1}O bond in ethyl alcohol relative to C{b1}O in methyl alcohol. 1952C. A. Coulson Valence v. 123 The asymmetry of charge, i.e. the polar character of the bond, sometimes called the degree of ionicity. 1960Nature 13 Aug. 590/1 In discussions..regarding bonding in inorganic semiconducting (or insulating) crystals there seems to be some confusion between bond ionicity on one hand and charge separation effects due to electronegativity differences on the other. 1966Bull. Amer. Physical Soc. XI. 187/1 The large hyperfine parameter for the NaCl structure is consistent with the expected greater ionicity. |
