  • The formula for the compound will contain both a cation and an anion to balance the overall charge of the compound. The cation is named normally and the anion is given the name of the actual anion. An easy way to recognize these formulas is the fact that they are made up of more that two elements and, usually, the first element is a metal. •Mar 07, 2018 · Can you name compounds and write chemical formulas for ionic and molecular compounds?

Then there is Cr2O7. So the NH4 we know is Ammonium, and then the rest of this Cr2O7 is dichromate. Now there is a prefix spot here, and that just happens to be the name of the anion that we have here. It's called dichromate. There are two atoms of Chromium, but the name of the anion is dichromate unlike the covalent compounds.

Name the non-metal (Oxygen) by replacing the ygen with ide. Look at the chemical formula to find the charge for Pb. O has an ionic charge of -2. Since there are two O atoms the total negative charge is -4. Therefore the lead must have a +4 for the compound to be balanced. We show that by putting a (IV) after the name for Pb.

Potassium dichromate, K 2Cr 2O 7, is a common inorganic chemical reagent, most commonly used as an oxidizing agent in various laboratory and industrial applications. As with all hexavalent chromium compounds, it is acutely and chronically harmful to health. It is a crystalline ionic solid with a very bright, red-orange color. The salt is popular in the laboratory because it is not deliquescent, in contrast to the more industrially relevant salt sodium dichromate.

The oxidation number of a Group 2 element in a compound is +2. The alkaline earth metals (group II) are always assigned an oxidation number of +2. Oxygen almost always has an oxidation number of -2, except in: peroxides (e.g. H2O2) where it is -1; compounds with fluorine (e.g. OF2) where it is +2 Mar 11, 2008 · Heterocyclic Compounds. Other elements such as nitrogen and oxygen can be included in the rings. When they are, the compounds are called heterocyclic compounds. The hetero- part of the name means that more than one kind of element is included within the ring and -cyclic, of course, indicates that there is at least one ring present in the compound.
