NAMING CHEMICALS – ionic compounds A. Name these ionic compounds (you will need your table of polyatomic ions): 1. 2. 3. 4. 5. 6. 7. 8. 9. AgCl AlF3 CaO NaI BeCl2 Mg(NO3)2 AgNO3 CuSO4 Al2(SO4)3 *Hopefully, you have noticed some have numbers and some don’t have numbers. That’s because atoms give and take different amounts of electrons when they are bonding, based on how many they have in their outermost or valence shell. Use the periodic table in your agenda from now on to figure out how to put in the correct number. Now wait for teacher for further explanation B. Give the chemical formula for the following ionic compounds (you will need your table of polyatomic ions): 1. copper 2 sulfate 10. aluminum oxide 2. copper 2 oxide 11. aluminum iodide 3. copper 2 chloride 12. aluminum sulphate 4. zinc oxide 13. iron 3 oxide 5. zinc fluoride 14. iron 3 phosphate 6. zinc sulphate 15. iron 3 chloride 7. silver nitrate 8. silver nitride 9. silver nitrite NAMING CHEMICALS – molecular compounds A. Name these molecular compounds: 1. NF3 2. NO 3. NO2 4. N2O 5. N2O4 6. PCl5 7. SF6 8. S2F10 9. NH3 (if you can figure out the common name for this, you get a candy) 10. PH3 B. Give the formula of the following ionic compounds 1. dihydrogen monoxide (you get a candy if you’re one of the first five people to come and tell me the common name of this compound) 2. dihydrogen monosulfide 3. dinitrogen tetrahydride 4. phosphorus trihydride 5. carbon tetrachloride 6. diphosphorus pentaoxide 7. sulphur dioxide
