Mixed Ionic/Covalent Compound Nomenclature: Mixed Ionic/covalent Compound Naming Answer Key
Mixed ionic/covalent compounds are compounds that contain both ionic and covalent bonds. They are typically formed between a metal and a nonmetal, with the metal losing one or more electrons to the nonmetal.
To name a mixed ionic/covalent compound, we first need to determine the oxidation states of the elements involved. The oxidation state of an element is the charge it would have if all of its bonds were ionic. Once we know the oxidation states, we can use the following rules to name the compound:
- The cation (positive ion) is named first, followed by the anion (negative ion).
- The name of the cation is the same as the name of the element.
- The name of the anion is the root of the element’s name, followed by the suffix “-ide”.
- If the metal is in a variable oxidation state, the oxidation state is indicated by a Roman numeral in parentheses after the name of the metal.
Here are some examples of mixed ionic/covalent compounds and their names:
- Sodium chloride (NaCl)
- Potassium oxide (K 2O)
- Calcium fluoride (CaF 2)
- Iron(III) oxide (Fe 2O 3)
- Copper(II) sulfate (CuSO 4)
Quick FAQs
