Lewis Structure

Is there a guideline you have to follow when doing Lewis Structures with multiple elements? For example, H2C(NH2)COOH.

Re: Text Book Problem 2.29 (d)

I see. So if you're given the quantum number "l" like in problem "a" then there would be 6 electron because it specifically asks for that orbital?

Text Book Problem 2.29 (d)

How many electron can have the following quantum numbers in an atom: n=2 To find 'l' you use (n-1) which gives you "1" that makes it a p-orbital (0,1). 'ml' is -1,0,1. That means that there are 6 electrons that can have that quantum number. But the book answer says there are 8 electrons. H...

Quantum Numbers

If the n (principle quantum number) is 3, then l (angular momentum quantum number) is 2. Which is a d-orbital. Where is the d oribtal when you have something like a 3s3p^3?

Resonance

A Lewis Structure that can be drawn differently but still be correct is Resonance? For instance a central atom can have one double bond with any of the three atoms surrounding it. Like in the Course Reader example on page 80.

Is light only emitted if the electron makes a transition down to a lower quantum level? Or is it emitted each time it moves to a different quantum level?
