Corinthian order perhaps reduced in size and importance, scrolling out above the two ranks of stylized acanthus leaves and stalks ("cauliculi" or "caulicoles"), eight in all, and to notice that smaller volutes scroll inwards to meet each other on each side. The leaves may be quite stiff, schematic and dry, or they may be extravagantly drilled and undercut, naturalistic and spiky. In Late Antique and Byzantine practice, the leaves may be blown sideways, as if by the wind of Faith. Unlike the Doric and Ionic column capitals, a Corinthian capital has no neck beneath it, just a ring-like astragal molding or a
Ionic compound by a specific equilibrium distance. If the electronic structure of the two interacting bodies is affected by the presence of one another, covalent interactions (non-ionic) also contribute to the overall energy of the compound formed. Ionic compounds are rarely purely ionic, i.e. held together only by electrostatic forces. The bonds between even the most electronegative/electropositive pairs such as those in caesium fluoride exhibit a small degree of covalency. Conversely, covalent bonds between unlike atoms often exhibit some charge separation and can be considered to have a partial ionic character. The circumstances under which a compound will have ionic or covalent
