Question

Quizplus · Accepted Answer

The Lewis symbol for aluminum is the letter "A" surrounded by dots, which signifies the three valence electrons of aluminum. Choice A is incorrect because it shows two Ga atoms sharing four valence electrons, while in reality, Ga has three valence electrons. Choice C is close, but it is missing one electron since the dot is only on the Al and not around it. Choice D is incorrect because Tl has three valence electrons, not two.
