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 ?

Options

  1. Aperiod 3, group 16
  2. Bperiod 3, group 17
  3. Cperiod 4, group 16
  4. Dperiod 4, group 17

Correct answer

A. period 3, group 16

Step-by-step 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.
