Iron binds four nitrogen atoms in the chelate complex of heme in hemoglobin because it allows for a stable coordination geometry. The four nitrogen atoms form a planar structure around the iron atom, which helps to stabilize the iron in the +2 oxidation state. This stable coordination geometry is essential for the function of hemoglobin, as it allows the iron to readily bind and release oxygen as needed in the body. Additionally, the chelate complex formation also helps to protect the iron atom from oxidation and degradation. **
