Question

Quizplus · Accepted Answer

- The [Ar] represents the electron configuration of Argon, which is the nearest noble gas to Se^2⁻. - The 4s subshell is filled before the 3d subshell. - The ^{2 means that there are two electrons in the S orbital, six electrons in the P orbital, and one electron in the upper level U.
- The} represents one electron in the 4p subshell. - Putting it all together, the electron configuration is [Ar] 4s²3d¹⁰4p⁶.
