3. Naming and Writing Ionic Formulas
Unit 6 Ch 9 Part 3
Naming and Writing Ionic Formulas

4. 9.2 Ionic Compounds
Binary compounds- 2 elements Binary ionic compounds- 1 metal + 1 nonmetal Binary molecular compounds- 2 nonmetals

5. When naming ionic compounds, simply name the ions as they appear in the formula.
When naming ionic compounds containing a transition metal, include the Roman numeral representing the charge.

6. Examples: NaCl NaF nonmetal metal CaCl2
**The more positive element (metal) always comes first.

7. Example: aluminum chloride AlCl3 KBr FeCl2 FeCl3 potassium bromide
iron(II) chloride
iron(III) chloride

8. Ionic Metal and Nonmetal _____VALENT METAL means:
_____________
Metals in group _____, _______, & these 4: __________________
Ex:
Rule:
Name the __________
then the __________ ending in ________.
_____VALENT METAL means: ___________________________
Located in ________ & under the __________________.
Same as mono- BUT use a ______________ to tell the metal’s __________.

9. Contains a polyatomic ion:
Ionic
Contains a polyatomic ion:
Ex:
Rule:
Follow the same mono- or multi- valent metal rules; use the polyatomic ion’s name.

10. When writing the formula for an ionic compound, the charges of the ions must cancel out to give the compound a neutral charge.

11. Example:
sodium chloride
Na+ Cl- 1 1
Na1Cl1 =
NaCl

12. magnesium iodide
Mg2+ I- 2 1
Mg1I2 =
MgI2

13. magnesium nitride
Mg 2+ N3- 2 3
Mg3N2

14. strontium selenide
Sr2+ Se2- 2 2 =
Sr2Se2
SrSe

15. rubidium iodide
Rb+ I-
RbI
aluminum oxide
Al3+ O2-
Al2O3

16. When writing formulas containing polyatomic ions, use parentheses around multiple polyatomic ions.
ammonium carbonate
NH4+ CO32- 2 1
(NH4)2CO3

17. strontium hydroxide
Sr2+ OH- 1 2
Sr(OH)2

18. calcium nitrate
Ca2+ NO3- 1 2
Ca(NO3)2

19. aluminum phosphate
Al3+ PO43- 3 3
AlPO4

20. When naming ionic compounds containing a transition metal, don’t forget to include the Roman numeral for the charge. Ex. FeCl2 iron(II) chloride FeCl3 iron(III) chloride

21. Tuesday Bellwork Match the following ions with their names.
___NO3- A. nitride
___CN- B. silver ion
___Ag+ C. cyanide
___NH4+ D. ammonium
___N3- E. chloride
___Cl- F. nitrate
