13 A chemist made the table below to record some atomic properties of four elements. Properties of Elements Element Number of Protons Number of Neutrons Total Number of Electrons Number of Electrons in Outer Shell B 5 5 5 3 9 10 9 7 Si 14 14 14 4 Ga 31 39 31 3 Based on the information in the table, which conclusion about the chemical reactivity of these elements is valid? A Boron is the most reactive because it has the most protons. B Fluorine is the most reactive because it has 7 electrons in the outer shell. c Silicon is the most reactive because it has an equal number of protons and neutrons. D Gallium is the most reactive because it has many more neutrons than protons. Madiam Cepeda
