Correct answer
AGroup 16 and period 5

Step-by-step explanation

As given, electronic configuration of valence shell (outermost shell) is 5s2 5p4..that means principle quantum number of valence shell is 5..As we know,principle quantum number of valence shell shows the 'period' of that element in periodic table..Hence period of the element is 5As there are total 6 electrons in valence shell or it similar to general valence shell configuration of group 16 i.e. ns2 np4,hence its group is 16..element correspond to period 5 and group 16
