Abundances in Przybylski’s star

I have reposted my blog article [1] to the study support group blog. I first posted this to my main blog [2]

This is a really interesting paper

  2. Paul Sutton — Personal Journal

I want to try and discuss this further, so would like to learn about

  1. Isotope shift
  2. How many neutrons needed to make an atom stable or less radio active, I think I understand the basic principle as to why it is harder to get more neutrons in to the atomic nucleus.

So also uploading the periodic table of isotopes for reference.
