CHM 101 When ionic compounds dissolve in water, they break apart into their component ions CHM 101 When ionic compounds dissolve in water, they break apart into their component ions.  Remember that some ions are monatomic ions, and others are polyatomic ions.  You will need to recognize polyatomic ions when they are part of the formula for an ionic compound.   For example, one formula unit of Na2CO3 contains three ions:  2 Na+ ions and 1 CO32- ion. How many ions are in just one formula ...
