Ions with 3, 4, or more oxygen atoms will have a suffix (end part) of…
“ate,” except acetate
(this pattern only really applies in this study set)
Ions with less than 2 oxygen atoms will typically have a suffix (end part) of…
“ite”
(this pattern only really applies in this study set)
If there is “Hydrogen” in the name, how many hydrogen atoms will be in the ion?
1 hydrogen atom
(Ex. hydrogen sulfate, hydrogen carbonate)
If there is “dihydrogen” in the name, how many hydrogen atoms will be in the ion?
2 hydrogen atoms
(Ex. dihydrogen phosphate)
If there is “ni” in the name, what will be in the compound?
nitrogen
(Ex. nitrite, nitrate, cyanide)
