Question

Quizplus · Accepted Answer

The ground-state electron configuration of selenium (Se) is [Ar]3d^10 4s^2 4p^4. This is because selenium is in the fourth period and is part of the p-block in the periodic table, specifically in group 16, indicating it has six electrons in its outermost p orbital (4p^6 when fully filled, but for Se, it's 4p^4 since it's two electrons short of being fully filled).
