Write the ground-state electron configuration of a samarium atom. A) [Xe]4f⁷5d¹ B) [Xe]5d⁸ C) [Xe]4f⁷6s¹ D) [Xe]4f⁸ E) [Xe]4f⁶6s²

Question

Quizplus · Accepted Answer

The ground-state electron configuration of samarium (Sm, atomic number 62) is [Xe]6s²4f⁶. This is represented in the given options in a non-standard notation, where "⁶6s²" corresponds to the correct configuration by counting the total number of electrons in the 4f and 6s orbitals after the [Xe] core.
