Web11 aug. 2024 · Aluminium or aluminum (13 Al) has 22 known isotopes from 22 Al to 43 Al and 4 known isomers. Only 27 Al (stable isotope) and 26 Al (radioactive isotope, t 1/2 = 7.2 × 105 y) occur naturally, however 27 Al comprises nearly all natural aluminium. Other than 26 Al, all radioisotopes have half-lives under 7 minutes, most under a second. WebAluminium (Al) has three isotopes, but only one can be found in nature and that is Al-27. The other isotopes of aluminium: 26 and 28 are unstable and radiate β-radiation. Their …

WebThese three isotopes have specific names: protium (A=1); deuterium (A=2); and tritium (A=3). Most elements occur naturally as MIXTURESof different isotopes, and an element’s ATOMIC WEIGHTis a weighted average of the isotopic mass of the element’s naturally occurring isotopes.
