Re: Final Jitters

I'm late at responding to this, but I know for this midterm I told myself I knew all the material before going in. I was able to successfully complete a practice exam prior to the official exam. Do some easy problems and just boost that confidence. Controlling your breaths also helps control jitters.

How do you differentiate between Atomic and Ionic Radius because I know they both increase when going down a group and decrease from left to right, so how are they different?

Re: M.9

I'm not completely sure how to find the ionic equation, but I believe you start off by balancing equations and then separating each element with its individual ionic charge and the number of each ion.
