Demystified Series

Did the question look something like

1s2 2s2 2p6 3s2 3p3.

except all the green numbers are superscript ( I don't know how to do that on here)

In the above question all you need to do is add the superscripts and the answer is 15 so Phospherus atomic numer 15 is the answer. It just looks harder and more complicated.

That's actually the part I understand.

Here's an example of one I don't understand...
An example of two electrons in the same orbital with paired spin quantum numbers (m subscript(s)) would be---
1) m(s)= +1/2,m(s)= -1/2 2)m(s)=+1,m(s)=+1 etc...

I actually just read this one again and I know what I did wrong. Paired electrons spin in opposite directions so the choice was +1/2,-1/2.

I think I'm going to have an issue because I did not memorize the periodic table. I assumed (incorrectly) that if a question referred to the atomic weight, etc. the chart would be provided.

I'm going to find one that was really confusing for me last night and post it. Since I'm studying multiple sources I need to find it. Thanks again!

Well I just finished another REA test and I scored 80% which they equate to a 68 on the exam. I'm not sure I trust that score but 80% is encouraging. I'm going to review what I missed, read up and clarify a few things then I'm going to relax until tomorrow. There isn't much more I can do at this point so it's all or nothing tomorrow. Even if I fail at least I'll be done with Natural Science because I will not be coming back to it later. milelol:

*EDIT* I forgot to add one thing...thanks to everyone for the guidance, encouragement, and help. :hurray:

I would say you should learn atomic numbers and symbols for some of the more common ones. Of course Carbon, Helium and Hydrogen, I would say the fist and last two columns are most important. Good Luck I will say a prayer for you.
