Slide1

Polyatomic Ions

Many ions are monoatomic BUTMost ions are polyatomic (>1 atom)

There are

five common polyatomic ions:nitrate NO

There are

five common polyatomic ions:note:

they all contain oxygen

they all end in –ATE

(signifies the most common form)

there’s no simple correlation between the number of

oxygens

and the charge

(easiest is to memorize)Slide4

Mnemonic (if they work for you; if not, memorize)Slide5
