Bassae a subtly curved floor, though the columns have entasis. The temple is unusual in that it has examples of all three of the classical orders used in ancient Greek architecture: Doric, Ionic, and Corinthian. Doric columns form the peristyle while Ionic columns support the interior and a single Corinthian column features in the centre of the interior. The Corinthian capital is the earliest example of the order found to date. It was relatively sparsely decorated on the exterior. Inside, however, there was a continuous Ionic frieze showing Athenians in battle with Amazons and the Lapiths engaged in battle with Centaurs.
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
