Question

Quizplus · Accepted Answer

The correct ground state electron configuration for selenium (Se) is [Ar] 4s2 3d10 4p4, which matches the configuration given in option D. Selenium has an atomic number of 34, meaning it has 34 electrons. The electron configuration builds upon the noble gas argon ([Ar]), followed by the filling of the 4s, 3d, and 4p orbitals in accordance with the Aufbau principle.
