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 Mourning Athena relief with Athena wearing a plain doric overfold chiton, c. 460 BC So-called "Exaltation de la Fleur" (exaltation of the flower), fragments from a secondary grave stele: two women wearing a peplos and kekryphalos , hold poppy or pomegranate flowers, and maybe a small bag of seeds. Parian marble, c. 470 –460 BC.
The chemical element of each atom is often indicated by the sphere's color. [ 2 ] In a ball-and-stick model, the radius of the spheres is usually much smaller than the rod lengths, in order to provide a clearer view of the atoms and bonds throughout the model.
A structural formula is a simplified model that cannot represent certain aspects of chemical structures. For example, formalized bonding may not be applicable to dynamic systems such as delocalized bonds. Aromaticity is such a case and relies on convention to represent the bonding. Different styles of structural formulas may represent ...
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.
An example of the difference is the empirical formula for glucose, which is CH 2 O (ratio 1:2:1), while its molecular formula is C 6 H 12 O 6 (number of atoms 6:12:6). For water, both formulae are H 2 O. A molecular formula provides more information about a molecule than its empirical formula, but is more difficult to establish.
It is unclear if chiton homing functions in the same way, but they may leave chemical cues along the rock surface and at the home scar which their olfactory senses can detect and home in on. Furthermore, older trails may also be detected, providing further stimulus for the chiton to find its home. [30]
For typical ionic solids, the cations are smaller than the anions, and each cation is surrounded by coordinated anions which form a polyhedron.The sum of the ionic radii determines the cation-anion distance, while the cation-anion radius ratio + / (or /) determines the coordination number (C.N.) of the cation, as well as the shape of the coordinated polyhedron of anions.
