atomic theory

[jinzen]

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

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?

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?

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)

c) What are the atomic numbers of their first three noble gases?

2, 10, 18

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 ^^
