The "Chemistry in Focus" segment A Magnetic Moment discusses the ability to levitate a frog in a magnetic field because electrons, when sensing a strong magnetic field, respond by opposing it. This is called diamagnetism. Atoms that are diamagnetic have all paired electrons. Which columns among the representative elements in the periodic table consist of diamagnetic atoms? Consider orbital diagrams when answering this question. (Select all that apply.)
