Nuclides vs isotopes A nuclide is a species of an atom with a specific number of protons and neutrons in the nucleus, for example carbon-13 with 6 protons and 7 neutrons. The nuclide concept (referring to individual nuclear species) emphasizes nuclear properties over chemical properties, while the isotope concept (grouping all atoms of each element) emphasizes chemical over nuclear.

The nuclide concept (referring to individual nuclear species) emphasizes nuclear properties over chemical properties, whereas the isotope concept (grouping all atoms of each element) emphasizes chemical over nuclear. Stable nuclides are the stable isotopes of all elements. Elements with atomic number less than 83 have at least one stable isotopes except technetium (Tc, Z = 41) and promethium (Pm, Z = 61). Elements with atomic number between 84 and 92 (inclusive) are present, but some only as decay products of uranium or thorium.

Isotopes of an Element. Atoms with the same atomic number but different mass numbers are isotopes of When referring to a single type of nucleus, we often use the term nuclide and nuclides — atoms with a specific number of protons and neutrons in their nuclei. In 2010, for the first time, more than 100 new unstable isotopes — nuclides with What is the difference between radiation and radioactivity? converted into a different isotope which may, according to its number of neutrons and protons, or disintegrates, the radioactive atom (radionuclide) transforms to a diffe 26 Jun 2015 How do we represent an atom, with all of its protons, neutrons, and electrons?

(= the atomic number) and the neutron number N. Since the mass of a nuclide is almost proportional to the number A A nuclide has a specific number of protons and neutrons, and will additionally have a as a more accurate substitute for the terms isotope and radioisotope.

Nuclides are specific types of atoms or nuclei. Every nuclide has a chemical element symbol (E) as well as an atomic number (Z) , the number of protons in the nucleus, and a mass number (A), the total number of protons and neutrons in the nucleus. The symbol for the element is as shown below: \[^A_{Z}E\] Iodine-129 is a rare long-lived radio-isotope of Iodine. I-129 is called a cosmogenic nuclide, because it is created by energetic cosmic rays impacting matter in a cosmic fission reaction, called spallation. It is also created artificially in nuclear fission reactions and naturally in nature by spontaneous uranium decay.
