Is aluminum a radioactive?
One of the isotopes of aluminium, namely aluminium-26 (26Al), contains 13 protons and 13 neutrons in its nucleus. Unlike the stable isotope aluminium-27 (27Al), which comprises an extra neutron, 26Al is radioactive and decays with an exponential lifetime of about one million years.
