Different Periodic Table?

  1. Apr 19, 2015 #1
    1. The problem statement, all variables and given/known data
    In the long form of periodic table, the valence shell electronic configuration of 5s2 5p4 corresponds to the element present in
    A. Group 16 and period 5
    B. Group 17 and period 6
    C. Group 17 and period 5
    D. Group 16 and period 6
    2. Relevant equations

    3. The attempt at a solution
    I know in normal periodic table 5s2 5 p4 corresponds to tellurium which is in group 16 and period 5.
    Don't know why the answer is group 17 and period 6 ?
    I think the long form of periodic table is same as normal periodic table.

    No idea what they mean, 5/16 looks OK to me.

    Long periodic table doesn't contain group 16 nor 17, so it is different.

    I am challenging the guys who said 6/17 is correct.
