WebO₂ is a diradical. The reaction when oxygen binds to hemoglobin is. Fe²⁺ + O₂ → Fe³⁺ + O₂·⁻ (Fe is oxidized; O₂ is reduced) The O₂·⁻ still has one unpaired electron. When low-spin Fe³⁺ binds to O₂·⁻, the spins of the two unpaired electrons couple strongly. (S = ½ - ½ = 0), so oxyhemoglobin is diamagnetic. WebFor example, the most powerful magnet in the world, neodymium-iron-boron magnets, only have 2 atoms of neodymium, 17 atoms of iron, and 1 atom of boron. So neodymium is not even the primary element in that compound. However, just having those 2 atoms of neodymium creates the best properties of any magnetic material out there.
