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. There are less and less electrons in an...

Determine the number of valence electrons in each of the following elements. NOTE: When electrons are added to the outermost d shell of a transition metal, sometimes the first electrons that go into the shell tend to act like normal valence electrons. This is not always the case, however. For the purpose of this problem, please count the outermost d electrons as among the valence electrons (even though they are not in an outermost d principal energy level. Part A...
