The content of neutron-capture (trans-iron-peak) elements in the low-metallicity galactic halo varies widely from star to star the differences are both in bulk amount of the neutron-capture elements with respect to lighter ones and in element-to-element ratios among themselves.

6 nucleosynthesis our planet has a lot of iron and silicon, along with many other elements the fact that there's a third peak at iron. Elements above iron in the periodic table cannot be formed in the normal nuclear fusion processes in stars up to iron, fusion yields energy and thus can proceed but since the iron group is at the peak of the binding energy curve, fusion of elements above iron dramatically absorbs energy (the.
