Binary ionic compound – ionic compound consisting of only 2 elements (monatomic ions)

Binary Compound – A compound with 2 elements more than 2 atoms = OK
(CaF
2
) more than 2 elements NOT ok
(NaCrO
4
)

Throwing in polyatomic ions:
If formula has more than 2 eles.
Names do not change
(no ide-ending)
!
a non-ide ending should clue you in (memorize hydroxide + CN -1 ) more than one ion = parenthesis

Check:
Is the compound binary?
Does it contain a transition metal?
If yes, use your ion sheet!!!
