Which element has the ground-state electron configuration [Xe]6s²? A) Re B) Ir C) Eu D) Gd

Question

Quizplus · Accepted Answer

The given electron configuration is incorrect and seems to be a typographical error. However, based on the context, it appears to be trying to describe an element with a ground-state electron configuration that follows xenon ([Xe]), then fills the 6s orbital partially or fully, which is characteristic of elements in the lanthanide series or just beyond. Europium (Eu) has the ground-state electron configuration [Xe] 4f7 6s2, which is closest to the pattern suggested by the erroneous configuration, assuming the intent was to describe an element in the lanthanide series with a distinctive electron configuration.
