3.04 - Polyatomic Ions - 14:06


KEY TERMS: 2 or more non-metals, Nick the Camel ate a Clam for Supper in Phoenix, "ate" ending

Underlined letter represents the atom
# of consonants = # of oxygens
# of vowels = # of negative charges associated with polyatomic
Ending is "ate" - except for ammonium ion and hydroxide ion

5 Step Cross over rule:
- Remember that polyatomic has brackets and the charge is written outside of the brackets
- remove brackets when the number outside of the brackets is a "1"javascript:void(0)
