Default atomic theory

This was an assignment given to us about atomic theory. The questions are in quotes and my answers/query are below the quotes.

Quote:
Construct a periodic table for these people on a different planet. Their atomic theory is the same as ours except that their spin quantum numbers are +1/2, 0 and -1/2 and their magnetic quantum numbers take the values 0, 1, 2, ... L
So... our spin quantum numbers are +1/2 and -1/2 and magnetic quantum numbers would be: L=0 m0 = 0, L=1 m1= -1,0,+1 etc. right?

Quote:
a) Everything else, including the ordering and naming of the orbitals will be the same. Only their spin quantum numbers and magnetic quantum numbers are different.
The only thing i don't get is how the magnetic quantum numbers are different than ours? Is it not the same? Or does the spin quantum numbers affect it? How so?

Quote:
b) Use atomic numbers instead of symbols and go as far as element 35
Yup, done that. I made a quick one:

Is that corrrect? (argg some of the lines disappeared o_o)

Quote:
c) What are the atomic numbers of their first three noble gases?
2, 10, 18

Quote:
d) What is the electron config of their elemt 24?
This i'm not so sure of, since i don't understand their spin quantum numbers. By +1/2, 0, -1/2... does tha "0" mean there can be a orbital that can be empty?

So... 1s2 2s2 2p6 3s2 3p6 4s2 3s9 ???

Thanks, I really appreciate the help to pointing out my errors ^^
