[Xe]6s²4f¹⁴5d¹⁰

Question

Which element has the following ground-state electron configuration [Xe]6s²4f¹⁴5d¹⁰ A) Lu B) Cd C) Hg D) Lr E) Au

Quizplus · Accepted Answer

The ground-state electron configuration listed contains the noble gas symbol for Xenon ([Xe]), indicating that all the electrons in the previous energy levels (up to 5p) are filled. The subsequent electron configurations show the filling of the remaining orbitals in the 6s, 4f, 5d, and 6p sublevels for a total of 80 electrons. The last orbital filled is the 6p0, which matches the electron configuration of mercury (Hg). Therefore, Choice C, Hg, is the correct answer.
