Quizplus · Accepted Answer

The electron configuration for the given element (O₂^-, which seems to be a coded representation) is not directly interpretable in standard chemical notation. However, assuming the question aims to test knowledge of electron configurations, the correct configuration for an element with a similar number of electrons to what might be inferred (16 electrons, as suggested by the correct option) is 1s^2 2s^2 2p^6 3s^2 3p^4, which corresponds to the element sulfur (S). The correct option (B) reflects an electron configuration ending in 2p^6, which is the filled p orbital in the second energy level, a key characteristic of the noble gas configuration in the second period, and aligns with the completion of the second shell.
