Abundances in Przybylski’s star
I have reposted my blog article  to the study support group blog. I first posted this to my main blog 
This is a really interesting paper
I want to try and discuss this further, so would like to learn about
- Isotope shift
- 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.
Comments / discussions welcome :)
