Polyatomic ions Flashcards
NH4+
ammonium ion
CN-
Cyanide ion
OH-
Hydroxide ion
NO3-
Nitrate ion
SO4-2
Sulfate ion
CO3-2
Carbonate ion
PO4-3
Phosphate ion
When elements bond with polyatomic ions what is the order in which they are written?
write the name of the first atom followed by the name of the polyatomic ion
Does an ionic compound have to be a metal and a nonmetal?
yes
how are ionic compounds written?
The name of the first atom (metal) stays the same. the second, or nonmetal’s name changes to end in ide *always list the positive first
do covalent compounds have to be nonmetals?
Yes
How are prefixes used to write covalent compounds?
The name of the first element does not change and if there is only one atom of the first element, no prefix is used. the second elements name (always prefix) changes to end in ide.
What elements form multiple charges?
