Iron-56 is ofte⁻n cite⁻d to be⁻ the⁻ most stable⁻ nucle⁻us, as it has the⁻ lowe⁻st mass-pe⁻r-nucle⁻on of any e⁻le⁻me⁻nt, and is the⁻ e⁻nd product of a lot of radioactive⁻ re⁻actions such as intraste⁻llar fusion. Howe⁻ve⁻r, de⁻spite⁻ be⁻ing far, far rare⁻r in its formation, nicke⁻l-62 is actually more⁻ stable⁻ by de⁻finition, having the⁻ highe⁻st binding e⁻ne⁻rgy pe⁻r nucle⁻on that we⁻ know of. This me⁻ans it would take⁻ more⁻ e⁻ne⁻rgy pe⁻r nucle⁻on to se⁻parate⁻ a nicke⁻l-62 nucle⁻us than an iron-56 one⁻. #funfacts #scie⁻nce⁻
