Re: Contributing to Resonance Structures

Yes, essentially. The most stable Lewis structure is always the one with the lowest energy.

Re: Formal charge purpose

Because you always want the lowest formal charge possible in order to have the most stable Lewis Structure. I heard from my TA that it is possible you will have to calculate formal charges for points on either Test 3 or the final.

Re: Isoelectronic [ENDORSED]

It means they have the same number of electrons. Ions of one element may be isoelectronic with uncharged atoms of another due to the gain/loss of electrons.

Cars, balls, etc. are too large (mass is too high) to exhibit noticeable wavelike properties.

Re: electron mass

Whether it makes a difference depends on the problem. Electrons do have mass, but it's extremely small. The exact value will probably be provided on the tests.

Re: Quiz #2 Question #2 B

Jumping down 2 levels (from n=5 to n=3) is a larger jump distance, which creates a lower wavelength and thus higher energy as far as I know.

Re: Homework 1.5

A lower wavelength means the frequency is higher because there are more waves in the same amount of time. So, because the frequency of gamma rays is the highest, their energy will also be the highest.

Re: Test 2

I'm pretty sure my TA said all of the necessary equations are provided on the test, so you probably just need to memorize what each variable represents.
