Question

Quizplus · Accepted Answer

Phosphorus has five valence electrons, so its Lewis symbol would show five dots around the chemical symbol. Argon has a full valence shell with eight electrons, so its Lewis symbol would show eight dots. Boron has three valence electrons, carbon has four, and sulfur has six, making phosphorus the only option with five valence electrons in its Lewis symbol.
