Which of the following elements in the third period would you expect to have the most negative electron affinity value, and why? Aluminum (Al), because it is a metal with a large atomic radius Chlorine (Cl), because it is a halogen with a high effective nuclear charge Silicon (Si), because metalloids release the most energy when gaining electrons Sodium (Na), because alkali metals only have one electron in the outer energy level
