The Ionic chiton could also be made from linen or wool and was draped without the fold and held in place from neck to wrist by several small pins or buttons.. Herodotus states the dress of the women in Athens was changed from the Doric peplos to the Ionic chiton after the widows of the men killed on military expedition to Aegina stabbed and killed the sole survivor with their peplos pins, each ...
The Ionic shaft comes with four more flutes than the Doric counterpart (totalling 24). The Ionic base has two convex moldings called tori, which are separated by a scotia. The Ionic order is also marked by an entasis, a curved tapering in the column shaft. A column of the Ionic order is nine times more tall than its lower diameter.
Ancient Greek in classical antiquity, before the development of the common Koine Greek of the Hellenistic period, was divided into several varieties.. Most of these varieties are known only from inscriptions, but a few of them, principally Aeolic, Doric, and Ionic, are also represented in the literary canon alongside the dominant Attic form of literary Greek.

In chemistry, a formula unit is the smallest unit of a non-molecular substance, such as an ionic compound, covalent network solid, or metal. [1] [2] It can also refer to the chemical formula for that unit. Those structures do not consist of discrete molecules, and so for them, the term formula unit is used.
The circumstances under which a compound will have ionic or covalent character can typically be understood using Fajans' rules, which use only charges and the sizes of each ion. According to these rules, compounds with the most ionic character will have large positive ions with a low charge, bonded to a small negative ion with a high charge. [25]
Some types of ionic compounds, however, cannot be written as empirical formulas which contains only the whole numbers. An example is boron carbide , whose formula of CB n is a variable non-whole number ratio, with n ranging from over 4 to more than 6.5.
Dissociation in chemistry is a general process in which molecules (or ionic compounds such as salts, or complexes) separate or split into other things such as atoms, ions, or radicals, usually in a reversible manner.
