Ionic order

Doric order; another is called Ionic order. Each of there had their format and requirement. They were based on different aspect: “By the end of the seventh century the Doric order emerged in mainland Greece, its intricate but austere patterns based on the timbering of earlier structures. Soon afterwards the east-Greek world contributed the Ionic order, based on orientalizing patterns of flower and scroll.” (Boardman 278) However, both orders were slower developed. The columns of both orders…

Covalent bonding occurs when atoms share pairs of electrons. Atoms will covalently bond with other atoms in order to gain more stability, which are gained by forming a full electron shell. By sharing their outer most valence electrons, atoms can fill up their outer electron shell and gain stability (Chem wiki) Nonmetals will readily form covalent bonds with other nonmetals in order to obtain stability, and can form anywhere between one to three covalent bonds with other nonmetals depending on…

Melting Point Generally, ionic solids have very high melting point temperatures. Covalent molecules have a lower melting point. Polar covalent molecules have a higher melting point than non-polar covalent molecules. 1. Mold an aluminum foil boat that will serve as a tray for the table salt, sugar, wax. 2. At different corners of the boat place a very small amount of each substance. a. Table Salt b. Sugar c. Wax 3. Set the hot plate on high. 4. Observe and record the order of melting of the…

chemical elements are bonded together. Two types of chemical bonds in compounds are covalent bonds and Ionic bonds. A covalent bond is the sharing of electrons between two or more atoms. They bond between two nonmetals or between two atoms with the same element. Two atoms with the same or similar electronegativity will not exchange an electron from their outermost shell, instead they share electrons in order to satisfy the octet rule. The octet rule states that atoms that have eight electrons…

experiment, qualitative analysis was used to identify two cations. Lead was identified in Part A, barium was identified in Part B and different flame colors were observed with various metal chloride solutions in Part C. Formula unit, total ionic, and net ionic equations were written for the confirmation reactions for both lead and barium. If this experiment was repeated, barium could be confirmed by the yellow precipitate BaCrO4 after confirming that the solution was clear and any excess…

Discussion of results: Multiple tests were done in order to identify and then confirm the identity of an unknown substance. The tests done to identify the compound included preliminary tests, solubility tests, and testing for anions and cations. In order to confirm the identity found, reactivity tests were then completed. The first test performed was a preliminary test that simply showed that the unknown compound was a powdery, white solid with no smell. A qualitative solubility test was…

Doric and Ionic orders – Orders that dealt with the Architecture of Greece. Doric order is the oldest of the orders, and also is much simpler than the Ionic order. The Doric order started showing up during the Geometric and Orientalizing Art period in mainland Greece, and is best seen in the Parthenon in Athens. The Ionic order is slightly more complex and came about a hundred years after the Doric order, beginning in the Ionian islands. The Temple to Athena Nike showcases Ionic order pillars.…

2.4 IL-DLLME procedures For IL-DLLME under optimum conditions, 10 mL of the sample solution containing Cd2+ or Ni2+ and PAN (10−5mol L−1) was adjusted to pH in a glass test tube with a conical bottom test tube. Using a microsyringe, the mixture of the extraction solvent ([Hmim][PF6]) and disperser solvent (acetonitrile) was rapidly injected into the previously mentioned aqueous sample. A cloudy solution (water, acetonitrile and [Hmim][PF6] ) was formed in the test tube. The ions reacted with…

different types of solids: ionic, polar covalent, non polar covalent, and metallic Hypothesis It is hypothesized the samples which are shown to be insoluble are likely non polar, while soluble samples are polar. Because of the molecular nature of each type of bond, it is hypothesized that polar covalent molecules It is hypothesized that the samples which are insoluble in water are likely to be non-polar molecules or network covalent and the samples which dissolve are either ionic or polar…
