     This previous week, we have done a lot of work hoping to get ready for our upcoming test. As a lot of us our more confused with the idea of Ions, it made it more difficult to really grasp how Ions are used, and really the concepts in general. Dr. J really wanted us to focus on worksheets given to us over the course of the week to help us get practice with what we were really struggling with. For me, going into the week, I had some trouble with using the charges to make them equal zero. It was very confusing at first when I had to apply it by myself.

     On Monday, we got a worksheet asking us to find the formulas for the atoms given, and then draw the particle diagram. On the back of that sheet, we were asked to put the formulas on a periodic table based on the atoms involved. As a class we then discussed the relationship between these formulas. I am glad we did because I honestly had no idea what the relationship ment. We concluded that the for formulas in each row, they have a specific charge. We then white boarded and we also concluded they a neutral atom becomes a positive ion by losing an electron, and becomes a negative ion by gaining an electron.

     The next day, we took another look at a different worksheet that focused on naming ionic compounds. This worksheet made us analyze different areas of the periodic table, that we used in the first worksheet, to determine specific charges for specific scenarios. It then game us two elements, and using so we had to come up with the most amount of formulas possible. This made us practice the fact that the sum of the charges always had to equal zero. It took a little bit of time for that to process in my mind, but over the course of the week it got easier to make the connection of how many of which is needed to equal zero. We were then given the opposite, where the formula was provided to us and we had to name the ionic compounds. It was great to be able to do this because it showed me both sides of ionic compounds and helped me understand where the fomulas are coming from, and vice versa.

     The next two days, we were given two more worksheets but these were really focused on the charges of the ions. The first worksheet focused on polyatomic ions and how they are given charges compared to monotomic ions. It gave us a deeper understanding of how they are similar and yet they are also different. We also did a worksheet that I found was the most helpful. It was a sheet that, in some cases, gave us the ions and we had to find the formula unit, and in other cases gave us the formula unit and we had to find the ions. We were also asked to name the ions. This really combined everything in one worksheet. It tested us on our ability to make the charges equal to zero, it gave us the chance to look up the names of the ions, and even find the specific number of ions and atoms in each formula unit.

     As we head towards our Unit 6 test on Monday, I reflect and think about how great it was of Dr. J to move the test back to Monday. This gave me the weekend to study and do this blog to really gather all the information I have learned and to look back on it. As we push towards our next unit, and slowly towards the end of the trimester, I am once again excited to see what we have left to learn before our final exam. I am pretty confident coming into this test Monday, hoping to obtain a famous mole.
