Detailed Solution
Download Solution PDFThe correct answer is 6.
Key Points
- The Elements of group 16 such as Oxygen, Sulfur, Selenium, Tellurium, Polonium and all have 6 electrons on the outermost cell.
- The 's' valence shells always contain 2 electrons, the 'p' valence shell contains 4 electrons.
-
The elements present in group 16 consist of oxygen (0), sulfur (S), selenium (Se), tellurium (Te), and polonium (Po).
- Of all the elements, only Polonium is radioactive.
- Group 16 electron configuration indicates that its members of Group 16 have six elements in its valence shell, and therefore require two elements to complete the octet valency.
- Therefore, all the elements of group 16 are negatively charged since they can receive two electrons from other elements.
