How do we know that Bismuth-209 is unstable?
I am very intrigued by the story that Bismuth was once believed to be the heaviest element with a stable isotope, until we learned that it is not stable due to some experiments in 2003. This is the ...

Fundamental question about particles losing mass during fusion
I have fundamental questions about why the strong force, when it brings particles to together to form a nucleus, triggers the particles to lose mass in the form of energy up until $\rm Fe$.
I had an ...

Do we compare Ni-62 and Fe-56 with different candidates when we choose the most tightly bound nucleus?
Quoting from Wikipedia:
$^{56}$Fe has the lowest nucleon-specific mass of the four nuclides listed in this table, but this does not imply it is the most strongly bound atom per hadron, unless the ...

How can decompressing neutronium accelerate beta decay to form heavy elements?
When neutron stars merge a large amount of nuclear material is ejected. Neutronium is only stable under extreme pressure. As it decompresses it is thought to turn into various heavy elements.
The ...
