We can use this as a clue Preview this quiz on Quizizz. Example-  Pb(NO3)4   write the name  "lead nitrate". For example, chromium can form Cr2+, Cr3+ or Cr6+. Let's make naming compounds super easy already! For naming multi - ionic compounds you must put roman numerals in the name, (Copper (I) Chloride-Total number of electrons is not equal to the total number of electrons-Cation, (positively charged atoms) is named first-Anion, (negatively charged atoms) is named last-For anion, you must remove the suffix/ending of the word and replace it with “ide”, e.g. For example, iron can form two common ions, Fe 2 + and Fe 3 +.To distinguish the difference, Fe 2 + would be named iron (II) and Fe 3 + would be named iron (III).. is cobalt (III) sulfide. The reason why I wrote Q: The edge length of the unit cell for nickel is 0.3524 nm. 4. Q. The Roman numerals after an ion indicate the charges and therefore help name the compound. write it here in the name. And so that's why we have to calcium phosphate. History- The type of naming you will learn about is called the Stock system or Stock's system. How do we name compounds when the cation of variable charge is involved? Titanium (II) chloride, and titanium (IV) chloride. Naming Ionic Compounds. You could say, okay if the I had a hard time in chem class cuz i don't know when to put the roman numerals if the ionic compound needed it. So we know that this is Check with your teacher.
