I am confused by the solution to 2.93. It says that A = Na, B = Cl. I understand that Na+ is larger than Cl-, but what is the trend for determining the relative sizes of atoms in their neutral state? Thanks.

I do not believe we need to know the specific ranges of wavelengths on the spectrum (x-rays, microwaves, radio waves, etc) though it would not hurt and I would definitely learn their general positions (longer/shorter wavelength). I know one question in the book asked which color in the visible spect...

∆E is the change in energy (final energy - initial energy). It seems that sometimes it will simply be written as E when in context it actually means ∆E.

I am pretty sure we were told we will not be tested on blackbody radiation, but it is an important concept for understanding the chapter overall.

At what point in this course should we know the molecular formulas for different molecules? (i.e. Nitric acid = HNO3)
