Question

Quizplus · Accepted Answer

The electron configuration given corresponds to the elements in Group 14 (also known as Group IV or the carbon group). The ns2np2 valence electrons indicate that the element is in the second row (n=2) and has two valence electrons in the p orbital. The ² and np⁴ sublevels indicate the specific energy level and sublevel electron configurations.
