No, it is a natural stable isotope.
false
Each isotope, stable or unstable, has a specific symbol; for example K-40 for potassium 40.
Hydrogen has 1 unstable isotope, and 2 stable isotopes.
A stable isotope does not decay and therefore, maintains a constant concentration on Earth. An unstable isotope, also known as a radioactive isotope, decays at a predictable and measurable rate on Earth. An unstable isotope may decay by the ejection of an electron or positron, known as beta decay, or by the ejection of two protons and two neutrons, known as alpha decay.
Succesive radioactive disintegrations in a radioactive series.
An isotope with too many neutrons can be unstable for example Hydrogen-3 is unstable while hydrogen-1 and 2 are stable. But so can one with too few neutrons, for example lead-204 is unstable while lead-206, 207, and 208 are stable.
The process is called decay, or sometimes nuclear decay. A link can be found below.
Bohrium is extremely unstable - the most stable isotope (270Bh) has a half life of only 61 seconds.
Technically the answer is false, however the answer most tests accept as the correct answer is True.According to Nuclear theory when a parent undergoes decay and produces a daughter isotope the daughter may be stable or it may be unstable and further decay until a final stable granddaughter isotope is formed. This process is called a decay chain, however since eventually a stable isotope is formed the acceptable answer is True, even though technically it is not the case.
Isotopes carbon-12 and carbon-13 are stable; the isotope carbon-14 is radioactive and unstable.
It will decay to a more stable lighter elements and release out some nuclear energy.
