For example, CaBr2 contains a metallic element (calcium, a group 2 (or 2A) metal) and a nonmetallic element (bromine, a group 17 (or 7A) nonmetal). Write the formula for the binary ionic compound: aluminum and nitrogen: AIN: Name the binary ionic compounds indicated by: AgCI: silver chloride: Name the binary ionic compounds indicated by: ZnO: zinc oxide: Name the binary ionic compounds indicated by: CaBr2: calcium bromide: Name the binary ionic compounds indicated by: SrF2: strontium fluoride: Name the binary ionic compounds indicated by: … Formulas and Nomenclature Binary Ionic Compounds Worksheet Name the following compounds. Take a look at the following examples to see how to use the prefixes when naming binary covalent compounds (the prefixes appear in bold). This system recognizes that many metals have two common cations. Write the final formula. It is not an ionic compound; it belongs to the category of covalent compounds discussed elsewhere. Now that we know how to name ions, we are ready to name ionic compounds. This is a clue that the other part of the formula, Ba, is actually the Ba2+ ion, with the 2+ charge balancing the overall 2− charge from the two nitrate ions. We do not call the Na+ ion the sodium(I) ion because (I) is unnecessary. If you are given a formula for an ionic compound whose cation can have more than one possible charge, you must first determine the charge on the cation before identifying its correct name. Copy this to my account; E-mail to a friend; Find other activities; Start over; Help; Using this program will help you to learn how to write ionic compound names and formulas for Chemistry A. Binary molecular compounds are generally composed of two nonmetal atoms conected by covalent bonds. Some anions have multiple forms and are named accordingly with the use of roman numerals in parenthesis. Thus, Na+ is the sodium ion, Al3+ is the aluminum ion, Ca2+ is the calcium ion, and so forth. You'll need to make sure you can quickly tell the type of chemical compound. Most ionic compounds are binary compounds, or compounds formed from just two elements. Sodium forms only a 1+ ion, so there is no ambiguity about the name sodium ion. The same issue arises for other ions with more than one possible charge. Binary ionic compounds formulas and nomenclature binary ionic compounds worksheet name the following start studying naming. Write the correct formula for an ionic compound. Nomenclature #2: Polyatomic Ionic Compounds 1. In the second compound, the iron ion has a 3+ charge, as indicated by the three Cl− ions in the formula. Write the final formula. iron (III) bromide. Some of the worksheets for this concept are formulas and nomenclature binary ionic nomenclature work 5 ionc compounds summary naming ions and chemical compounds naming ionic compounds work i since we use different methods in naming binary … The key difference between ionic and binary compounds is that ionic compounds contain two charged components whereas binary compounds contain two different chemical elements.. Ionic compounds are binary compounds that come under two different categories. 4. Nonmetal atoms are found in the upper right of the periodic table, although hydrogen is sometimes included in this group. 4. The cation has the same name as its element. For more information contact us at info@libretexts.org or check out our status page at https://status.libretexts.org. Binary acids. The formula for aluminum oxide is Al 2 O 3. 3. This means that the two cobalt ions have to contribute 6+, which for two cobalt ions means that each one is 3+. Give the correct formula and chemical name for the ionic compound: {eq}K^+ {/eq} and {eq}Cl^- {/eq} Ionic Compounds: Ions are formed when atoms of an element gain or lose electrons. CK-12 Foundation by Sharon Bewick, Richard Parsons, Therese Forsythe, Shonna Robinson, and Jean Dupon. The word ion is dropped from both parts. For example, Sodium has a +1 charge and Chloride has a -1 charge, so the ionic compound would be named Sodium Chloride. The rest of the rules will be outlined in the following example. Example \(\PageIndex{7}\): Sulfur Compound. Ionic compounds are named by stating the cation first, followed by the anion. This method may be used to name any binary ionic compound, but in the instance of mono-valent metals it’s redundant and so not employed.
