Lesson 5 - Naming Compounds (Nomenclature0.pptx

presentation about naming ionic and molecular compounds

1. Naming Compounds

2.  1. Is it an Ionic Compound or a Molecular Compound? It is  Ionic  if it has a  metal  (an element on the left or middle of the periodic table) It is  Molecular  if it has  two nonmetals  (elements on the right side of the periodic table above the staircase, plus hydrogen)

3. IONIC COMPOUNDS

4. 2. Add an ‘ide’ to the end of the second compound’s name For  both molecular and ionic  compounds, change the name of the second compound so it  ends in ‘ide’ ex: fluorine = fluoride, hydrogen = hydride

5. 1. Potassium and Phosphorus

6. 2. Calcium and Sulfur

7. 3. Barium and Nitrogen

8. 4. Aluminum and Selenium

9. 5. Gallium and Phosphorus

10. 3. Ionic Compounds with Transition Metals For Ionic Compounds with transition metals, you need to  insert a roman numeral  after the name of the metal to  indicate the transition metal’s charge ex: FeCl = Iron(I) Chloride and FeCl 2 = Iron(II) Chloride

11. iron (III) chloride

12. titanium (IV) oxide

13. MnBr 4

14. CoP

15. 4. Polyatomic Ions - an ion composed of more than one atom .

16. Since there are  no ionic charges to balance  out in  molecular   compounds , you need to use  prefixes  (see chart) ex: N 2 O 5 = dinitrogen pentoxide For the  first element , you  don’t need  to say  ‘mono’ ex: CO = carbon monoxide (not monocarbon monoxide)
