WebThese are very rare, as on Earth they are only produced through the fission of heavy radioactive elements (for example, uranium or thorium ). Both elements have been identified spectroscopically in the atmospheres of stars, where they are produced by ongoing nucleosynthetic processes. Web16 jul. 2012 · Importantly, it can be seen that the rarity or supply risk of an element in this case does not necessarily directly correlate with the elements’ abundance on the Earth. An element, for example gold, may have a low crustal abundance giving it a high risk score of 5 in terms of scarcity, but it may also be evenly distributed across the globe.
