Very interesting chart. Thank you for sharing. Can you explain the gray radioactive isotopes more? What does "nothing left from
stars" mean?
@joekunk the chart is for the material that the solar system consists of - so material that has been created more than 4.5 billion years ago (age of solar system). The grey elements are the ones where all isotopes have a short half-life (time needed so half of what is there decays) - so by today pretty much nothing of them is left!
