The name of the anion ends in "-ate". The compound’s name is iron(II) phosphate. Ternary compounds are composed of three or more elements. Similarly, O2− is the oxide ion, Se2− is the selenide ion, and so forth. 0. To name a compound, the cation name and the anion named are added together. The name consists of a cationic part and an anionic counterpart, assuming ionic behavior in covalent compounds too. Table \(\PageIndex{1}\) lists the elements that use the common system, along with their respective cation names. A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The name of a monatomic anion consists of the stem of the element name, the suffix -ide, and then the word ion. CopyCopied, Validated by Experts, Validated by Users, Non-Validated, Removed by Users, Predicted data is generated using the ACD/Labs Percepta Platform - PhysChem Module. In the second compound, the iron ion has a 3+ charge, as indicated by the three Cl− ions in the formula. :: Chemistry Applications:: If we were to use the stems and suffixes of the common system, the names would be ferrous chloride and ferric chloride, respectively (Figure \(\PageIndex{3}\)) . ChemSpider ID 9079110. This means that the one iron ion must have a 2+ charge. Chloride always has a 1− charge, so with two chloride ions, we have a total negative charge of 2−. The name of the compound is aluminum phosphate. Practice until it becomes second nature. K - University grade. It is often called more simply aluminum trifluoride, or even aluminum fluoride. Thus, Fe2+ is called the iron(II) ion, while Fe3+ is called the iron(III) ion. The name Alf is in the following categories: Mythological Names, Nordic Names, Norwegian Names, Scandinavian Names. iron(II) phosphate For example, consider FeCl2 and FeCl3 . To add the "-ide" ending, just drop the 1 or 2 syllables ("-ine" in this case), and add "-ide" instead. KF, CaI2, AlP, Ga2O3, PBr3, Co2O3, K2SO4, GaBr3. CopyCopied, NOBTYUUWOBTGLI-UHFFFAOYSA-L Last Post. By the Stock system, the names are iron(II) chloride and iron(III) chloride (Figure \(\PageIndex{2}\)). aluminum phosphate: c. Neither charge is an exact multiple of the other, so we have to go to the least common multiple of 6. Edit. The compound’s name is iron(II) phosphate. The polyatomic ion name stays the same. We do not call the Na+ ion the sodium(I) ion because (I) is unnecessary. 1. Get more practice naming compounds. A binary ionic compound is a compound composed of a monatomic metal cation and a monatomic nonmetal anion. Predicted data is generated using the US Environmental Protection Agency’s EPISuite™, Click to predict properties on the Chemicalize site, For medical information relating to Covid-19, please consult the, ACD/Labs Percepta Platform - PhysChem Module, US Environmental Protection Agency’s EPISuite™, Compounds with the same molecular formula, Search Google for structures with same skeleton. No predicted properties have been calculated for this compound. These common names make use of prefixes, such as iso-, sec-, tert-, and neo-.The prefix iso-, which stands for isomer, is commonly given to 2-methyl alkanes.In other words, if there is methyl group located on the second carbon of a carbon chain, we can use the prefix … To get 6+, three iron(II) ions are needed, and to get 6−, two phosphate ions are needed . 4 years ago. Al has a +3 charge and F has a -1 charge and its name is Aluminum fluoride because it is an ionic compound. Yes thank you! 2. The fluorine atoms are ligands. 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 names of negative ligands end in "-o". Thus, the name of the fluoride ion becomes "fluorido" when it is a ligand. Nomenclature and compounds DRAFT. The name of this ionic compound is aluminum fluoride. Add the name of the non-metal with an –ide ending. Cl is chlorine. The second system, called the common system, is not conventional but is still prevalent and used in the health sciences. Thus, as we have already seen, Cl− is “chlor-” + “-ide ion,” or the chloride ion. 1 decade ago. Table \(\PageIndex{2}\) lists the names of some common monatomic ions. This means that the two cobalt ions have to contribute 6+, which for two cobalt ions means that each one is 3+. 0% average accuracy. What is the correct name for the compound AlF3? Write the name of the cation. Answer Save. Example \(\PageIndex{3}\): Naming Ionic Compounds. Certain branched alkanes have common names that are still widely used today. Learning to name chemical compounds requires that you: Determine the type of compound you are working with. Average mass 64.978 Da. c. Neither charge is an exact multiple of the other, so we have to go to the least common multiple of 6. (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… Relevance. The name of this ionic compound is potassium chloride. The fullest correct name is monoaluminum trifluoride. Alfa Aesar 12851 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. Using the names of the ions, this ionic compound is named calcium chloride. What do you call a metal and/ or non metal compound? *UNLESS the anion is a polyatomic ion. b. For Al 2 S 3 use the hints and resources below to help write the name. Write the proper name for each ionic compound.
