Question

Quizplus · Accepted Answer

Carbon and silicon both belong to the same group (group 14) in the periodic table, which means they have the same number of valence electrons (4). Option A is incorrect because carbon has 6 electrons while silicon has 14 electrons. Option C is incorrect because carbon has 6 electrons while oxygen has 8 electrons. Option D is incorrect because carbon has 4 valence electrons while nitrogen has 5 valence electrons. Option E is incorrect because carbon has 4 valence electrons while aluminum has 3 valence electrons.
