Stable isotope — Graph of isotopes/nuclides by type of decay. Orange and blue nuclides are unstable, with the black squares between these regions representing stable nuclides. The unbroken line passing below many of the nuclides represents the theoretical… … Wikipedia
Isotopes of oxygen — Late in a massive star s life, 16O concentrates in the O shell, 17O in the H shell and 18O in the He shell There are three stable isotopes of oxygen that lead to oxygen (O) having a standard atomic mass of 15.9994(3) u. 17 radioactive isotopes… … Wikipedia
Isotopes of caesium — Caesium (Cs) has 40 known isotopes. The atomic masses of these isotopes range from 112 to 151. Only one isotope, 133Cs, is stable. The longest lived radioisotopes are 135Cs with a half life of 2.3 million years, 137Cs with a half life of 30.1671… … Wikipedia
Isotopes of technetium — Technetium (Tc) is one of the two elements in the first 82 that have no stable isotopes (in fact, it is the lowest numbered element that is exclusively radioactive); the other such element is promethium. [ LANL Periodic Table , Technetium… … Wikipedia
Isotopes of nitrogen — Natural Nitrogen (N) consists of two stable isotopes, nitrogen 14, which makes up the vast majority of naturally occurring nitrogen, and nitrogen 15. Fourteen radioactive isotopes (radioisotopes) have also been found so far, with atomic masses… … Wikipedia
Isotopes of neodymium — Naturally occurring neodymium (Nd) is composed of 5 stable isotopes, 142Nd, 143Nd, 145Nd, 146Nd and 148Nd, with 142Nd being the most abundant (27.2% natural abundance), and 2 radioisotopes, 144Nd and 150Nd. In all, 33 radioisotopes of Neodymium… … Wikipedia
Isotopes of chromium — Naturally occurring chromium (Cr) is composed of four stable isotopes; 50Cr, 52Cr, 53Cr, and 54Cr with 52Cr being the most abundant (83.789% natural abundance). 50Cr is suspected of decaying by β+β+ to 50Ti with a half life of (more than)… … Wikipedia
Isotopes of molybdenum — There are 33 known isotopes of molybdenum (Mo) ranging in atomic mass from 83 to 115, as well as four metastable nuclear isomers. Seven isotopes occur naturally, with atomic masses of 92, 94, 95, 96, 97, 98, and 100. Of these naturally occurring… … Wikipedia
Isotopes of niobium — Naturally occurring niobium (Nb), element 41, is composed of one stable isotope (93Nb). 93Nb is the lightest nuclide theoretically susceptible to spontaneous fission, and although this has never been observed, it makes niobium theoretically the… … Wikipedia
