Honors Chemistry is designed for students who have demonstrated strong ability in previous science courses. In this fast-paced, demanding course, the main topics--which include atomic theory, nuclear chemistry, periodicity, chemical reactions, stoichiometry, gases, solutions, reaction kinetics, equilibrium, acid-base theory, oxidation-reduction, and organic chemistry--are studied at an advanced level, with an focus on both conceptual understanding and problem-solving. Quantitative aspects of chemical concepts are emphasized throughout the course. Laboratory experimentation is an integral part of this class, and students write a number of formal reports which require demonstration of a sophisticated understanding of the relevant theories and principles.
Phosphate ion PO Pattern 1: For instance, if you know nitrate is NO3-,then nitrite is NO If you know phosphate is PO,then you know phosphite is PO You can also use the prefixes hypo- and per- with the chlorate series. Hypochlorite is a double whammy: You can also substitute the other halogens for Cl and make additional sets of the series.
The -ates with charges less than negative 1 that is, ions with charges of -2, -3, etc. HCO3-is called either the bicarbonate ion or the hydrogen carbonate ion.
These are named hydrogen phosphate and dihydrogen phosphate, respectively. That means you need to see the naming acids rules. The following periodic table will also come in handy. Working backward from the halogens, or 7A family, the oxidation states are most commonly -1, while the 6A family is -2, and the 5A family is Naming acids is extremely easy if you know your polyatomic ions.
There are three rules to follow: HCl is hydrochloric acid; H2S is hydrosulfuric acid.
When you see an acid name beginning with hydro- think: HCN is an exception since it is a polyatomic ion without oxygen, so it is named hydrocyanic acid. If the acid has an -ate polyatomic ion after the H, that makes it an -ic acid.
H2SO4 is sulfuric acid. When the acid has an -ite polyatomic ion after the H, that makes it an -ous acid. H2SO3 is sulfurous acid.Formulas and Nomenclature Binary Ionic Transition Metals Worksheet Name the following compounds.

Learning Objectives. By the end of this section, you will be able to: Define ionic and molecular (covalent) compounds; Predict the type of compound formed from elements based . Although ionic compounds are composed of both positively and negatively charged ions, the overall compound and its formula are electrically neutral. Writing a formula for ionic compounds containing polyatomic ions also involves the same steps as for a binary ionic compound. Write the symbol and charge of the cation followed by .
SO2 sulfur dioxide! 4. SO3 sulfur trioxide! 5. N 2O dinitrogen monoxide! 6. NO nitrogen monoxide! 7. N2O3 dinitrogen trioxide!
8. NO2 nitrogen dioxide! 9. N2O4 2 dinitrogen tetroxide! N2O5 dinitrogen pentoxide PCl3 phosphorous trichloride! Naming Chemical Compounds - Answers Name the following ionic compounds: 1) NaBr sodium bromide 2) CaO calcium oxide 3) Li 2S lithium sulfide 4) MgBr 2 magnesium bromide 5) Be(OH) 2 beryllium hydroxide Write the formulas for the following ionic compounds: 6) potassium iodide KI 7) magnesium oxide MgO 8) aluminum chloride AlCl 3.
Ionic Compounds Containing a Metal and a Polyatomic Ion. Metals combine with polyatomic ions to give ionic compounds. Name the cation first (specifying the charge, if necessary), then the polyatomic ion as listed in the table above (or as derived from the rules which were given).
