Beryllium (4Be) has 11 known isotopes and 3 known isomers, but only one of these isotopes (9 Be ) is stable and a primordial nuclide. As such, beryllium...

unstable isotopes of beryllium are created in stars, but the radioisotopes do not last long. It is believed that most of the stable beryllium in the universe...

then decreases until it reaches a local minimum at helium-4. Isotopes of lithium, beryllium, and boron are less strongly bound than helium, as shown by...

deuterium, but the new studies of spallation showed that this process could generate lithium, beryllium and boron; indeed, isotopes of these elements are over-represented...

is the kinetic isotope effect: due to their larger masses, heavier isotopes tend to react somewhat more slowly than lighter isotopes of the same element...

This is a list of radioactive nuclides (sometimes also called isotopes), ordered by half-life from shortest to longest, in seconds, minutes, hours, days...

cause of the iodine pit phenomenon. With the exception of beryllium, tellurium is the second lightest element observed to have isotopes capable of undergoing...

radioactive isotopes were produced: the heavy hydrogen isotope tritium (3H or T) and the beryllium isotope beryllium-7 (7Be). These unstable isotopes later...

naturally occurring beryllium and is its only stable isotope; however other isotopes have been synthesised. In ionic compounds, beryllium loses its two valence...

formation processes of the two stable isotopes of helium produce the differing isotope abundances. Equal mixtures of liquid 3 He and 4 He below 0.8 K separate...
