6 Naming Ionic Compounds with Two Elements To name a compound that contains two elementsIdentify the cation and anion.Name the positive metal ion (cation) as the element.Name the anion by changing the ending to ide.Name the cation first followed by the name of the anion.
20 Naming FeCl2 To name FeCl2; 1. Determine the charge of the cation using thecharge of the anion (Cl-).Fe ion Cl- = 1(?) (1-) = 0Fe ion = Fe2+2. Name the cation by the element name and aRoman numeral in parenthesis to show charge.Fe2+ = iron(II)3. Write the name of the anion with an ide ending.iron(II) chloride = FeCl2
21 Naming Cr2O3To name Cr2O31. Determine the charge of cation from the anion (O2-).2Cr ions O2- = ? (2-) = ? - 6 = 0? = / 2Cr ions = +3Cr ion = Cr3+2. Name the cation by the element name and use aRoman numeral in parenthesis to show its charge.Cr3+ = chromium(III)3. Write the name of the anion with -ide ending.chromium (III) oxide = Cr2O3
