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 is an essential mineral and an important component of proteins involved in oxygen transport and metabolism Almost two-thirds of the iron in your body is found in hemoglob â¦ in, the protein in red blood cells that carries oxygen to your body's tissues. Smaller amounts of iron are found in myoglobin, a protein that helps supply oxygen to muscle, and in enzymes that assist biochemical reactions in cells. About 15 percent of your body's iron is stored for future needs and mobilized when dietary intake is inadequate. The remainder is in your body's tissues as part of proteins that help your body function. Adult men and post-menopausal women lose very little iron except through bleeding.
