Transition Metals and Roman Numerals
Pg 4—check your answers
• Homework: page 5 #1-10 on top
Polyatomic Ions Quiz-Quiz Trade
• Take a card, find a partner
• Partner A reads partner B’s question out loud,
then answers.
• Partner B confirms or corrects Partner A’s
answer.
• Do the same thing in reverse.
• Trade cards
• Find a new partner and quiz-quiz-trade
Naming Compounds with Polyatomic
Ions (Page 5)
• Naming compounds with polyatomic ions is
EASY!
– Metal + polyatomic ion
– Polyatomic ion + nonmetal-ide
– Polyatomic ion + polyatomic ion
• These are IONIC, so NO prefixes!
Naming Compounds with Polyatomic
Ions (Page 5)
• Examples for your notes:
ZnSO4
NH4Cl
NH4OH
Na3PO4
Al2(SO4)3
Cu(NO3)2
• Homework: page 5 #1-10 on bottom
Making ionic compounds: names and
formulas
• Find the ions listed for each number.
• Make the positives and negatives balance!
• For 1-10, write the name and balanced
formula
• For 1-7, also sketch the compound
