What is a cation afraid of?Answer: A dogion…
Many ionic compounds are not binary Many ionic compounds are not binary because one or both ions contain because one or both ions contain atoms of more than one element. atoms of more than one element.
These These polyatomic ions consist of two polyatomic ions consist of two or more different non-metal atoms, or more different non-metal atoms,
which are joined by covalent bondswhich are joined by covalent bonds. . There is only one common There is only one common
polyatomic cation: the ammonium polyatomic cation: the ammonium ion, NHion, NH44
++.. There are many There are many polyatomic anions. polyatomic anions. Except for the Except for the
hydroxide ion, the names of thehydroxide ion, the names of the
anions end inanions end in
““-ate-ate””
instead of “ide”.instead of “ide”. Writing formulas is Writing formulas is also the same, except that you have to also the same, except that you have to
add parentheses when the formula add parentheses when the formula requires more than one polyatomic requires more than one polyatomic
