While, the contribution of Mg to soil dispersion is apparently very low, it has been calculated against ionicity values developed from a small subset of soils.
Categorical variables including sex, abnormal routine hematologic investigations, administered contrast volume subgroups, and the ionicity of the contrast were compared using chi-square tests.
Usually, the magnitude and sign of Q(A) characterize the ionicity of atom A in the supercell, while [Q.sub.A-B] can be used to approximate the average covalent bonding strength between atoms A and B.
Ionicity is the characteristic of a molecule to break up into a cation and an anion, resulting in more molecules per kilogram of water and thus increasing osmolality.
Marchuk and Rengasamy (2011), on the premise that water stability of soil aggregates depends on the degree of ionicity of clay-cation bonding, derived the ionicity indices of monovalent and divalent cations in relation to their bonding with clay particles and showed that these indices dictate clay behaviour in aqueous suspensions.

Therefore, Marchuk and Rengasamy (2011) concluded that the degree of ionicity or covalency of a cation will reflect the degree of covalent or ionic character of clay-cation bonds.
Recently, Marchuk and Rengasamy (2011), on the basis that the degree of ionicity in a clay-cation bond affects clay dispersion, derived the ionicity indices for various cations bonded to clay.
As noted above, the size and number of organic molecules binding the iodine are the primary determinant of the ionicity, osmolality, and viscosity of the commercial product.
The degree of covalency or ionicity in a bond involving a metal cation is characterised by the Misono softness parameter derived from their ionisation and ionic potentials (see Rengasamy and Sumner 1998, for more details).
