Homework Help: Quantum Numbers. Help really needed!

  1. Mar 17, 2007 #1
    1. The problem statement, all variables and given/known data

    a)write a ground state electron configuration of for the arsenic atom
    b)give a possible set of quantum numbers for each of the three outermost electrons of the arsenic atom


    i know how to get the ground state, but i have no idea how to get the quantum number for each of the three electrons. I search google also, all i've found is articles regarding the ground state. At this point I am 100% stuck. thanks for help!
