In the long form of the periodic table, the
valence shell electronic configuration of
5s2 5p4
corresponds to the element present
in :
(1) Group 16 and period 6
(2) Group 17 and period 5
(3) Group 16 and period 5
(4) Group 17 and period 6
There are 6 vlaence electrons in s and p orbitals so group number is 16.
As valence shell is 5, the element has 5 shells and hence the period is 5.
Option 3 is correct, Group 16, period 5
As valence shell is 5, the element has 5 shells and hence the period is 5.
Option 3 is correct, Group 16, period 5
