Iron Fe
- Naturally occurring iron consists of four stable isotopes: 5.845% of 54Fe, 91.754% of 56Fe, 2.119% of 57Fe and 0.282% of 58Fe. File:FE54 56 57 sigma.png

Lead Pb
- Lead can be found or produced in many isotopes, with three of them being stable. The four natural isotopes of lead are 204Pb, 206Pb, 207Pb, and 208Pb with the slightly radioactive 204Pb regarded as completely primordial lead Wikipedia
