iÂ·onÂ·ic bond. A chemical bond formed between two ions with opposite charges. Ionic bonds form when one atom gives up one or more electrons to another atom. These bonds can form between a pair of atoms or between molecules and are the type of bond found in salts.
The answer is supernovae. In a supernova explosion, neutron capture reactions take place (this is not fusion), leading to the formation of heavy elements. This is the reason why it is said that most of the stuff that we see around us come from stars and supernovae (the heavy elements part).
Iron in Your Body. The majority of your bodyâs iron is found in hemoglobin, the part of red blood cells that carries oxygen for delivery to your cells. Hemoglobin is a highly complex molecule that has one atom of iron at its center. That one atom is what gives blood its red coloring.
