### Constants and Equations Page

I noticed that on the constants and equations page the formula for formal charge was not on there. Does that mean that we would have to memorize it for midterm 2?

Yes, you will have to memorize this equation, but hopefully the equation will stick in your head after using it so many times.

Yes we will have to memorize it. Anything not on the formula sheet needs to be memorized.

Yep have to memorize but here is how I remember it:

Freddy Can't Vacant Nashville Before 2

FC = V - N - B/2

Not sure how helpful that is for you, but it sticks in my head.

I also have a question on the Constants and Equations page. I noticed the equation that gives the energy of n in Hydrogen is En=-h/n^2. Is the missing R a typo or is it written like that on purpose? Thanks!

The Rydberg constant (R) should be in the formula. On the online version its in a different font and italicized. It appears very lightly when printed, so maybe that's why it didn't appear on your sheet.
