To which group and period does the element belong if the electronic configuration of an element in its -2 oxidation state is $1 s^2 2 s^2 2 p^6 3 s^2 3 p^6 ?$
period 3, group 16
period 3, group 17
period 4, group 16
period 4, group 17
Solution
Electronic configuration $=1 s^2, 2 s^2, 2 p^6, 3 s^2, 3 p^6$ $=16$ electrons
Sulphur $(Z=16)$ refer to group 16 and period 3 .
Sulphur show -2 oxidation state.
