Naming and Writing Ionic Compounds
There are a lot of ways to write ionic compounds, one way in Criss Cross Applesauce which uses the criss cross method is fairly simple. It helps balance out the charges in an ionic compound.
Here is the difference between the positive and negative ions:
Cations: when metal atoms lose electrons to for positive charged ions.
Monatomic Cations: cation formed from a single atom Metal Groups 1,2,3, Ag ,Cd,Zn form one ion.
Multiple Ions can get a little tricky. These usually include transition metals and groups 3-5.
you must find out what the charge of the ion is. The formula for this is: Element Name ( charge) + Ion
Anions:when non-metal atoms gain electrons to form negatively charged ions
Monatomic Anions:anion formed from an individual anion
The formula is: Element Stem Name + “ide” + ion
Polyatomic Ion: groups of atoms that lose or gain electrons
