AP EAMCET · Chemistry · Classification of Elements and Periodicity in Properties
To which group and period does the element belong if the electronic configuration of an element in its -2 oxidation state is \(1 s^2 2 s^2 2 p^6 3 s^2 3 p^6 ?\)
- A period 3, group 16
- B period 3, group 17
- C period 4, group 16
- D period 4, group 17
Answer & Solution
Correct Answer
(A) period 3, group 16
Step-by-step Solution
Detailed explanation
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.
