Isotopes of aluminium

Aluminium has several isotopes, but the most notable and stable isotopes are: 1. **Aluminium-26 (\(^26\text{Al}\))**: This is a radioactive isotope with a half-life of about 730,000 years. It is produced through cosmic ray interactions and is significant in astrophysical studies and in dating geological formations.

Aluminium-26 (often written as \(^{26}\text{Al}\)) is a radioactive isotope of aluminium. It has a nucleon count of 26, consisting of 13 protons and 13 neutrons. \(^{26}\text{Al}\) is notable for its half-life of about 717,000 years, which allows it to be used in various scientific studies.
