Re: How have your study habits changed?

I stopped trying to read the textbook before starting the textbook problems from the outlines. At first I thought that we were supposed to read the chapters, but now I understand that it is almost never necessary and it is more beneficial to finish the problems rather than read. This is probably the...

Re: Valence Electrons

An easy way to find the number of valence electrons is by using the group that an atom is in. Group one atoms have 1 valence electron and those in group 8 (noble gases) have 8 valence. Do not count the d block while counting the groups.

Re: M(l) Quantum Number

m(l) depends on the value of l. If l=1, then m(l) can equal -1,0, or 1.
If l=2, then m(l) can equal -2,-1,0,1,2.

So if the problem says that n=2, l=1, m(l)= 1
then it would be referring specifically to the "2pz" state.

Re: d orbitals

This means that there are five orbitals in a d sub-shell. Since we know that one orbital holds two electrons, and that a d sub-shell can contain up to ten electrons, we can say that ten divided by two is five. Therefore, there are five orbitals in the d sub-shell.

Re: Rearranging De Broglie Equation

wavelength(lambda) = planck's constant(h) / momentum(p)
p = mass x velocity
you can plug in mv for p in the wavelength equation and isolate v
you would end up with

v = h/m(lambda)

Re: Order of Balancing Rxns

I find it beneficial to make a chart and list the number of each type of atom on either side of the equation. As I balance things, I cross them off the list. This helps me visualize what has been balanced and what has not. It makes it easier compared to doing it all in my head.
