Homework Statement
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!
