Ba(NO 3) 2 9. NAMING CATIONS Cations that can have only one charge, such as Na⁺ and Mg²⁺ have the same name as the metal … From a list of almost 2000 names and formulas, students will be given the opportunity to practice their ability to name ionic compounds, given the formula, and determine the formula given the name. Ionic compounds are named after the ions that form them. Title: Microsoft Word - 6-16a-Names of Ionic Compounds Wkst-Key.doc Author: Brent White Created Date: 6/21/2005 9:35:58 PM The Metal loses e- and becomes a cation (+). There are two ways to recognize ionic compounds. Ionic compounds form when positive and negative ions share electrons and form an ionic bond.The strong attraction between positive and negative ions often produce crystalline solids that have high melting points. Zn(CN) 2 16. Al(ClO 3) 3 4. The second part of the compound name is the name of the negative ion. The first thing we need to do is figure out what kind of compound we are working with, as ionic and covalent compounds have very different naming systems. Examples: nitride, sulfide, fluoride, oxide, bromide, iodide, chloride, telluride, phosphide. NH 4 OH 11. index 11 For example, CaBr 2 contains a metallic element (calcium, a group 2 [or 2A] metal) and a nonmetallic element (bromine, a group 17 [or 7A] nonmetal). Mg 3 (PO 4) 2 3. Sr(HCO 3) 2 6. Cr(OH) 3 18. Monatomic Positive Ions. Naming Ionic Compounds Containing Polyatomic Ions. Cs 2 CrO 4 10. CuClO 3 17. Metal is listed first, followed by nonmetal. The chemical name of an ionic compound is based solely on the identities of the ions that it contains.Specifically, the names of the ions are modified by removing the word "ion" from each, and the remaining terms are written in the order in which they appear in the corresponding ionic chemical formula. CaSO 4 5. Their names consist of two parts: The first part of the compound name is the name of the positive ion. Co 2 (CO 3) 3 14. As with simple ionic compounds, these compounds must also be electrically neutral, so their formulas can be predicted by treating the polyatomic ions as discrete units. Ionic compounds are made up of a metal cation (named first) and a non-metal anion (named second). PbSO 3 13. The Nonmetal gains e- and becomes an anion(-). NaNO 3 7. Many ionic compounds contain polyatomic ions as the cation, the anion, or both. https://www.khanacademy.org/.../v/naming-ions-and-ionic-compounds Ionic bonds form instead of covalent bonds when there is a large difference in electronegativity between the ions. Li 2 CO 3 8. Therefore, it is most likely an ionic compound. NAMING IONIC COMPOUNDS The name of an ionic compound is name of cation + name of anion (two words) You will have to memorize the formulas of the common ions. We use parentheses in a formula to indicate a group of atoms that behave as a unit. One you have done that, you can follow the following rules to generate the names. FeCl 2 12. First, compounds between metal and nonmetal elements are usually ionic. Naming Ionic Compounds. AgNO 3 15. Ionic Compounds Contain a metal and a nonmetal. Name Ionic Compound 1. The names of ionic compounds are written by listing the name of the positive ion followed by the name of the negative ion. Recognizing Ionic Compounds. Naming Ionic Compounds When Given the Formula. KCH 3 CO 2 2. Change the name of the nonmetal to -ide.
