An element, such as copper, is a substance that has been broken down as far as it can be using chemical means. Each element is made up of just one kind of atom. Copper has an atomic number of 29 on the periodic table. Answer and Explanation: ...
Medical radioisotopes such as iodine also lie outside what is known as the band of stability, but, in this case, they offer beneficial characteristics. Iodine-131 has four extra neutrons than its stable counterpart, and has a half-life of eight days. Since iodine can be safely ingested, it...
An element is defined by the number of protons in its nucleus, so this process transforms iron into heavier elements, like gold, in what is almost a form of cosmic alchemy. It is theradiation from the decay of the radioactive elementscreated during the r-process that makes the material eje...

Ahalogenis an element in the 7th column of the periodic table, such as fluorine, chlorine, bromine, iodine and astatine. Astatine is one of the rarest naturally-occurring elements, and iodine is not really used in our industry, leaving us with the former three. ...
In other words, every atom that is releasing some kind of radiation can be tracked and therefore, the element's overall radioactivity can be recorded. More importantly, these machines test to see what kind of radiation it is emitting (alpha, beta, gamma, etc). When the machine picks up ...
