Intro to Ionic Bonding and Ionic Compound Formulas Writing

We have currently been studying about chemical formulas and have been learning how to equal them. With this worksheet to the left was the first time we tried playing with the chemicals inside foods we eat. We looked at cat food, granola bars, kidney beans and such. We found these chemicals on the label of the product. Surprisingly there were many chemicals in each product I looked at.

Here are the all the products I looked at and the name of the compound and the Ionic Compound that goes with it. As you can See the compound have numbers and subscripts that go along with an element. They look hard to do but they are actually really easy. Here is and example of a compound and the Ionic Compound that goes with it: Potassium Chloride: KCl it goes this way because Potassium has a positive charge of 1 and Chloride has a negative charge of 1 so the cancel out to KCl with no sub numbers but Tin Sulfide will have a subscript of 2 because Tin has a positive charge of 2 and Sulfide has a negative charge of 1 so you cross the 2 over and the -1 over and you get SnS2 but the two will be a subscript. 

This is another worksheet (left) as a reference to show how to do these.  Also I have some book work( below) to show how awesome I am at these Ionic Compound.
