Quizplus · Accepted Answer

The notation ²⁴Mg seems to be a misinterpretation of the electronic configuration. For magnesium (Mg), the correct electronic configuration is 1s² 2s² 2p⁶ 3s², indicating that the second energy level (which includes both the 2s and 2p orbitals) has a total of 8 electrons (2 in the 2s orbital and 6 in the 2p orbital).
