Oxygen radioactive isotopes
WebRadioactive isotopes have a variety of applications. Generally, however, they are useful because either we can detect their radioactivity or we can use the energy they release. … WebIsotope Facts. All elements have isotopes. There are two main types of isotopes: stable and unstable (radioactive). There are 254 known stable isotopes. All artificial (lab-made) isotopes are unstable and therefore radioactive; scientists call them radioisotopes. Some elements can only exist in an unstable form (for example, uranium).

There are three known stable isotopes of oxygen (8O): O , O , and O . Radioactive isotopes ranging from O to O have also been characterized, all short-lived. The longest-lived radioisotope is O with a half-life of 122.266(43) s, while the shortest-lived isotope is O with a half-life of 198(12) yoctoseconds.

Tellurium-128 undergoes beta-decay with a half-life estimated to be 7.7 x 10 24 years.
WebFor example, in a typical terrestrial sample of oxygen, 99.76% of the O atoms is oxygen-16, 0.20% is oxygen-18, and 0.04% is oxygen-17. Any nucleus that is unstable and decays …
WebJan 1, 2016 · Stable isotopes are variants of atoms that differ in mass but do not decay over time, that is, they are not radioactive. The element oxygen (O) is found in three naturally occurring stable isotopes, 18 O, 17 O, and 16 O. The nucleus of each of these oxygen isotopes contains eight protons and either eight, nine, or ten neutrons, respectively. hp 89a blackWebFurther information about an unknown radioactive isotope can be identified simply by analyzing the radiation that it shoots out of the isotope. Gamma radiation produces photons, beta decay produces electrons or positrons, and alpha decay releases entire alpha particles (helium nuclei).
