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).
How Your Body Uses Iron in Food. When you eat food with iron, iron is absorbed into your body mainly through the upper part of your small intestine. There are two forms of dietary iron: heme and nonheme. Heme iron is derived from hemoglobin.It is found in animal foods that originally contained hemoglobin, such as red meats, fish, and poultry. Your body absorbs the most iron from heme sources. Nonheme iron is from plant sources.ow Your Body Uses Iron in Food.
