Chemistry Electron Configuration Questions

I do not understand anything about electron configuration. How do you figure out if the element is in P,D,S,orF? What do the subscripts represent? What is a subshell? I am so confused!!

You figure it out by using the Aufgau principle, placing electrons in the proper order in orbitals

I suggest a tutoring by another student on this, it is really simple, you are having undoubtably a mental block. It is rather difficult to teach on a text format.

It is really simple..

Here is an interactive site that may be of help. Bob Pursley found this and I saw it yesterday.

  1. Hi i'm not sure if you still need the answers but here they are (in condensed form):

    P: [Ne] 3s2 3p3
    Li: [He] 2s1
    Ca: [Ar] 4s2
    Ga: [Ar] 3d10 4s2 4p1
    As: [Ar] 3d10 4s2 4p3
