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, after all, is essential to life. Most iron in our bodies is incorporated in hemoglobin, which carries oxygen in the blood, and in myoglobin in muscle, but every living cell has and needs iron to function. Iron is also stored in the liver, spleen and bone marrow.Without it, your cells would become starved for oxygen, your brain and muscles wouldnât function, and your immune system would be impaired, among other problems.ost iron in our bodies is incorporated in hemoglobin, which carries oxygen in the blood, and in myoglobin in muscle, but every living cell has and needs iron to function.
