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 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. The shaft itself is eight diameters high. The architrave of the entablature commonly consists of three stepped bands (fasciae). The frieze comes without the Doric triglyph and metope.
In most cases the formula representing a formula unit will also be an empirical formula, such as calcium carbonate (CaCO 3) or sodium chloride (NaCl), but it is not always the case. For example, the ionic compounds potassium persulfate ( K 2 S 2 O 8 ), mercury(I) nitrate Hg 2 (NO 3 ) 2 , and sodium peroxide Na 2 O 2 , have empirical formulas of ...
In the earlier Doric temples the intercolumniation is sometimes less than one diameter, and it increases gradually as the style developed; thus in the Parthenon it is 1 1 / 4 , in the Temple of Diana Propylaea at Eleusis, 1 1 / 4 ; and in the portico at Delos, 2 1 / 2 .
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 condensed matter physics and inorganic chemistry, the cation-anion radius ratio can be used to predict the crystal structure of an ionic compound based on the relative size of its atoms. It is defined as the ratio of the ionic radius of the positively charged cation to the ionic radius of the negatively charged anion in a cation-anion ...
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
For most ionic compounds dissolved in water, the van 't Hoff factor is equal to the number of discrete ions in a formula unit of the substance. This is true for ideal solutions only, as occasionally ion pairing occurs in solution. At a given instant a small percentage of the ions are paired and count as a single particle.
