Corinthian order girl, as thick and much taller than a Doric one, which is designed to represent the bulk and vigour of a muscular full grown man. The oldest known example of a Corinthian column is in the Temple of Apollo Epicurius at Bassae in Arcadia, c. 450–420 BC. It is not part of the order of the temple itself, which has a Doric colonnade surrounding the temple and an Ionic order within the cella enclosure. A single Corinthian column stands free, centered within the cella. This is a mysterious feature, and archaeologists debate what this shows: some state that it is
Ionic bonding cannot exist, as the proximity of the entities involved in the bonding allows some degree of sharing electron density between them. Therefore, all ionic bonding has some covalent character. Thus, bonding is considered ionic where the ionic character is greater than the covalent character. The larger the difference in electronegativity between the two types of atoms involved in the bonding, the more ionic (polar) it is. Bonds with partially ionic and partially covalent character are called polar covalent bonds. For example, Na–Cl and Mg–O interactions have a few percent covalency, while Si–O bonds are usually ~50% ionic and ~50% covalent.
