Which of these elements would have the highest number of valence electrons? Phosphorus Beryllium Bromine Sulfur Which of these elements requires the highest amount of energy to remove a valence electron resulting in the formation of a cation? Boron Carbon Oxygen Sodium Atomic radius increases down a group (family) because: There are less and less protons in an atom. There are more and more electrons in an atom and electrons take space.
