Chemistry - PERIODIC TABLE Question with Solution | TestHub

$As given, electronic configuration of valence shell (outermost shell) is 5s^2 5p^4..that means principle quantum number of valence shell is 5..$$$\begin{gathered} As we know,principle quantum number of valence shell shows the \text{'}period\text{'} of that element in periodic table.. \\ Hence period of the element is 5 \end{gathered}$$$$\begin{gathered} As there are total 6 electrons in valence shell or it similar to general valence shell configuration of group 16 i.e. n{s}^2 n{p}^4,hence its group is 16.. \\ element correspond to period 5 and group 16 \end{gathered}$$
