    a) Si

    n = 3 l = 0 m = 0 s = 1/2

    n = 3 l = 0 m = 0 s = -1/2

    n = 3 l = 1 m = -1 s = 1/2

    n = 3 l = 1 m = 0 s = 1/2

    b) K

    n = 3 l = 0 m = -1 s = -1/2

    n = 3 l = 1 m = 0 s = -1/2

    n = 3 l = 1 m = 1 s = -1/2

    n = 4 l = 0 m = 0 s = 1/2

    c) Zn

    n = 4 l = 2 m = -2 s = -1/2

    n = 4 l = 2 m = -1 s= -1/2

    n = 4 l = 2 m = 0 s= -1/2

    n = 4 l = 2 m = 1 s= -1/2

    curiously, you are able to no longer call 4 the two, yet you are able to bypass on a protracted diatribe against the protection tension. i do no longer think we've bombed 4 international locations interior the final 2 weeks, in spite of the certainty that that is lifelike to have self belief that we've used explosive munitions in the two Afghanistan or Iraq. someway i do no longer see undemanding a thank you to equate maintaining our interests to imperialism.
