The condensed electron configuration of magnesium,element 12,is ________. A) [He]2s⁴2p⁴ B) [Ne]2p⁸ C) [Ne]3s² D) [He]2s² E) [He]2s⁶

Question

Quizplus · Accepted Answer

The electron configuration of magnesium is 1s2 2s2 2p6 3s2. To write the condensed electron configuration, we start with the symbol of the previous noble gas, which is neon (Ne) for magnesium. Then, we write the valence shell configuration, which is 3s2. Thus, the condensed electron configuration of magnesium is [Ne]3s2. Among the choices given, only option C matches this configuration, which is [Ne]3s², with the superscripts representing electrons filled in the corresponding subshells.
