(e) none of the above the answer is________

  • Chemistry -

    M = 2s + 1
    s = (1/2)*5
    Looks like M = 6 to me.

  • Chemistry -

    Could you help me with the second one as well please?

  • Chemistry -

    The answer to the second one is (a) because its the most electronegative.

  • Chemistry -

    No, I can't help with part B.
