Isotopes

International Isotopes Inc. manufactures a wide range of calibration and reference standards for nuclear medicine, generic sodium iodide I-131 drug product for hyperthyroidism and thyroid cancer. Isotopes are atoms of the same element with different numbers of neutrons. Because they contain different numbers of neutrons, isotopes have different atomic masses. The average atomic mass of an element is calculated by taking the weighted average mass of the element's naturally occurring isotopes. Stable isotopes. A stable isotope is an atom that, although it has either a lack or an excess of neutrons, won ’ t decay or disintegrate. You can find many examples of stable isotopes among the elements with a low atomic number. These include: Copper: Copper 63 and Copper 65. Carbon: Carbon 12 and Carbon 13. Hydrogen: Hydrogen 2 and Hydrogen 1.. Sep 02, 2022 · Isotopes are the elements that have the same number of electrons and protons but a varying number of neutrons.
