A model of tin, an element with the atomic number 50, is shown here. The valence electrons are modeled here in this image. Which statements are supported by the information in the model? Select ALL That apply. A) Tin needs four more electrons to complete its outer shell. B) Tin has no neutrons in the nucleus, as is shown in the model. C) Tin is highly reactive because it only has four valence electrons. D) Tin is negatively charged because it more electrons than protons. E) Tin has a low reactivity because it has full inner shells of electrons.
