tantalum
…is in one stable isotope, tantalum-181. However, a small amount, 0.012 percent, is tantalum-180, which has the unusual property of being found in its excited state. The tantalum-180 excited state has a half-life of more than 1.2 × 10¹⁵ years; the ground state (the lowest energy state) has a half-life…
