Question

Quizplus · Accepted Answer

To determine the noble gas electron configuration of the cation, we first need to find the electron configuration of the neutral atom of the element. The element in this case is ruthenium (Ru), which has an electron configuration of [Kr]5s24d6. Next, we need to remove electrons to form the cation. The cation is Ru⁺, which means that one electron is removed from the 5s orbital, one electron is removed from the 4d orbital, one electron is removed from the 6s orbital, one electron is removed from the 5p orbital, and one electron is removed from the 4s orbital. Therefore, the noble gas electron configuration of the cation is [Kr]5s¹4d⁶, which is represented by choice (E).
