Two which group and period does the element belong if the electronic configuration of an element in its -2 oxidation state is `1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)` ?

Options

A. period 3, group 16
B. period 3, group 17
C. period 4, group 16
D. period 4, group 17

Answer

A

Explanation

Electronic configuration `=1s^(2), 2s^(2), 2p^(6), 3s^(2), 3p^(6)=16` electrons
Sulphur (Z=16) refer to group 16 and period 3.
Sulphur show - 2 oxidation state.
