Preferred Label : ionic bond;
IUPAC definition : The bond between atoms with sharply different electronegativities. In strict terms,
an ionic bond refers to the electrostatic attraction experienced between the electric
charges of a cation and an anion, in contrast with a purely covalent bond. In practice,
it is preferable to consider the amount of ionic character of a bond rather than referring
to purely ionic or purely covalent bonds. The relationship was proposed (L. Pauling)
for the estimation of ionic character of a bond between atoms A and B: \[{Amount of
ionic character} 1 - e {-1/4}\ (\chi _{{A}}\,-\,\chi_{{B}})\] where χ A and χ B
are the Pauling electronegativities of atoms A and B. This type of bonding is realized
mostly in solids.;
