We do not call the Na+ ion the sodium(I) ion because (I) is unnecessary. Iron, for example, can form two cations, each of which, when combined with the same anion, makes a different compound with unique physical and chemical properties. The metal cation is named first, followed by the nonmetal anion as illustrated in Figure \(\PageIndex{1}\) for the compound BaCl2. Edit. 14-31-36/37/38 Alfa Aesar 12851: 8/26/1937 12:00:00 AM Alfa Aesar 12851: DANGER: FLAMMABLE, irritates skin, eyes, lungs Alfa Aesar 12851: DANGER: WATER REACTIVE, POISON, causes headache, nausea. There are two ways to make this distinction. Write the name of the anion and change the ending to -ide. Common compound names. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds; or through the sharing of electrons as in covalent bonds . 0% average accuracy. Figure \(\PageIndex{1}\) is a synopsis of how to name simple ionic compounds. Answer Save. To get 6+, three iron(II) ions are needed, and to get 6−, two phosphate ions are needed . Cl is chlorine. The polyatomic ions have their own characteristic names, as discussed earlier. In the simpler, more modern approach, called the Stock system, an ion’s positive charge is indicated by a roman numeral in parentheses after the element name, followed by the word ion. This means that the two cobalt ions have to contribute 6+, which for two cobalt ions means that each one is 3+. The name of this ionic compound is aluminum fluoride. InChI=1S/Al.2FH/h;2*1H/q+2;;/p-2 Example \(\PageIndex{5}\): Naming Ionic Compounds. 2. The name of the #"AlF"_6^(3-)# ion is hexafluoridoaluminate.

Iron can also have more than one possible charge. We know that cobalt can have more than one possible charge; we just need to determine what it is. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. Two ammonium ions need to balance the charge on a single sulfide ion. I had to do about a hundred of these things and I wasnt sure about those. :: Chemistry Applications:: Oxide always has a 2− charge, so with three oxide ions, we have a total negative charge of 6−. Legal. jerry758. (it can however have a valency of 4, by obtaining a +1 charge, but if that is the case, it will be in the name… The -ic suffix represents the greater of the two cation charges, and the -ous suffix represents the lower one. Favorite Answer. Examples of molar mass computations: NaCl , Ca(OH)2 , K4[Fe(CN)6] , CuSO4*5H2O , water , nitric acid , potassium permanganate , ethanol , fructose . Causes Of Arthritis After Pregnancy. AlF3. Last Post. Learning to name chemical compounds requires that you: Determine the type of compound you are working with. 2. Thus, we need a different name for each iron ion to distinguish Fe2+ from Fe3+. Monoisotopic mass 64.978348 Da. Therefore, the proper name for this ionic compound is iron(II) chloride. aluminum phosphate: c. Neither charge is an exact multiple of the other, so we have to go to the least common multiple of 6. Practice until it becomes second nature.

Sodium forms only a 1+ ion, so there is no ambiguity about the name sodium ion. This page was constructed from content via the following contributor(s) and edited (topically or extensively) by the LibreTexts development team to meet platform style, presentation, and quality: CK-12 Foundation by Sharon Bewick, Richard Parsons, Therese Forsythe, Shonna Robinson, and Jean Dupon. Positive and negative charges must balance. This means that the one iron ion must have a 2+ charge. difluoroaluminum. For Al 2 O 3 use the hints and resources below to help write the name. In the first compound, the iron ion has a 2+ charge because there are two Cl− ions in the formula (1− charge on each chloride ion). To get 6+, three iron(II) ions are needed, and to get 6−, two phosphate ions are needed . 3 0. Adopted a LibreTexts for your class? After learning a few more details about the names of individual ions, you will be one step away from knowing how to name ionic compounds. ChemSpider ID 9079110. The fullest correct name is monoaluminum trifluoride. The name Alf is in the following categories: Mythological Names, Nordic Names, Norwegian Names, Scandinavian Names. The polyatomic ion name stays the same. Learning to name chemical compounds requires that you: Determine the type of compound you are working with. The common system uses two suffixes (-ic and -ous) that are appended to the stem of the element name. The name of a monatomic anion consists of the stem of the element name, the suffix -ide, and then the word ion. The ammonium ion has a 1+ charge and the sulfide ion has a 2− charge. The second component of an ionic compound is the non-metal anion. Table \(\PageIndex{2}\) lists the names of some common monatomic ions. Apply the rules for naming that type of compound. The same issue arises for other ions with more than one possible charge. Start studying Ionic Compounds Names and Formulas. Na+ Br-NaBr Sodium Bromide 2. 0 times. c.

Similarly, O2− is the oxide ion, Se2− is the selenide ion, and so forth. xH2O, these compounds include monohydrate (x = 1), two polymorphs of the trihydrate (x = 3), a hexahydrate (x = 6), and a nonahydrate (x = 9). K - University grade. Edit. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Add the name of the non-metal with an –ide ending. Ask Question + 100. a. 1. These are two different compounds that need two different names. This section begins the formal study of nomenclature, the systematic naming of chemical compounds. It is often called more simply aluminum trifluoride, or even aluminum fluoride. Using the names of the ions, this ionic compound is named calcium chloride. Names? The name of the anion ends in "-ate". Save. If we were to use the stems and suffixes of the common system, the names would be ferrous chloride and ferric chloride, respectively (Figure \(\PageIndex{3}\)) . Get your answers by asking now. The process of naming ionic compounds with polyatomic ions is the same as naming binary ionic compounds. To use the rules for naming ionic compounds. Unless otherwise noted, LibreTexts content is licensed by CC BY-NC-SA 3.0. Name: Aluminum Fluoride. Since polyatomic compounds involve polyatomic IONS, you use similar rules to ionic nomenclature. Example \(\PageIndex{3}\): Naming Ionic Compounds. Certain branched alkanes have common names that are still widely used today.

We have seen that some elements lose different numbers of electrons, producing ions of different charges (Figure 3.3). Molar mass calculator also displays common compound name, Hill formula, elemental composition, mass percent composition, atomic percent compositions and allows to convert from weight to number of moles and vice versa. The enzymes increase electron-attraction by the carbonyl group, some (Class I) forming a protonated imine with it, others (Class II), mainly of microbial origin, polarizing it … The cation is named first, followed by the anion. Example Reactions: • 2AlCl3 + 6NH4F = Al2F6 + 6NH4Cl. Ternary compounds are composed of three or more elements. Lv 7. If either the cation or the anion was a polyatomic ion, the polyatomic ion name is used in the name of the overall compound. The formula is already given in the question; the name of the compound is aluminum trifluoride. Predict the chemical formula of the ionic compound formed between Al and F. Expresses answer as a chemical formula. Using Common Names with Branched Alkanes. Unless anything else is specified we assume aluminium to have a valency of 3.
