The electronic configuration for aluminum is 1s²2s²2p⁶3s²3p¹.The valence configuration for sulfur is:

Question

Quizplus · Accepted Answer

The valence configuration for an element is determined by the electrons in its outermost shell. For sulfur, the outermost shell is the third shell, which includes the 3s and 3p subshells. The electronic configuration given for sulfur includes these subshells along with others from lower energy levels, but only the electrons in the outermost shell are considered valence electrons. Therefore, the valence configuration for sulfur is 3s²3p¹. Choice D is the only option that includes this configuration.
