Source sentences:
text: Outside the nucleus, free neutrons are unstable and have a mean lifetime of 14 minutes, 42 seconds.
text: Neutrons bound in atomic nuclei can be stable, as they are when they occur in the familiar chemical elements, but they can also give rise through weak decays to the type of radioactivity known as beta decay.
text: Molybdenum-98 combines with a neutron to give molybdenum-99, an unstable isotope that emits a β particle to yield an excited form of technetium-99, represented as 99Tc*.
text: Free neutrons are unstable particles which decay naturally into a proton and electron, with a half-life of about 12 minutes.
text: A neutron alone in space is unstable.
text: A free neutron is unstable, decaying to a proton, electron and antineutrino with a mean lifetime of just under 15 minutes (881.5±1.5 s).
text: Neutrons or protons bound in a nucleus can be stable or unstable, however, depending on the nuclide.
text: Outside the nucleus, free neutrons are unstable and have a mean lifetime of 880.2±1.0 s (about 14 minutes, 40 seconds); therefore the half-life for this process (which differs from the mean lifetime by a factor of ln(2) = 0.693) is 610.1±0.7 s (about 10 minutes, 10 seconds).
text: Free neutrons are unstable, although they have the longest half-life of any unstable subatomic particle by several orders of magnitude.
text: Carbon-12 is stable but carbon-14 which has 2 extra neutrons is unstable.
text: Neutrons or protons bound in a nucleus can be stable or unstable, however, depending on the nuclide.
text: While a free neutron has a half life of about 10.2 min, most neutrons within nuclei are stable.
text: For example, Carbon-12 (6 protons and 6 neutrons) is stable, while Carbon-14 (6 protons and 7 neutrons) is radioactive.
text: However, it is remarkable that neutrons, when they exist together with protons in the nucleus of atoms, are stable.
text: Molybdenum-98 combines with a neutron to give molybdenum-99, an unstable isotope that emits a β particle to yield an excited form of technetium-99, represented as 99 Tc*.
