Hypothetical stable isotope of Promethium?

Click For Summary
SUMMARY

The discussion centers on the theoretical creation of an artificial stable isotope of Promethium, specifically referencing Promethium-147, which is classified as semi-stable with a half-life of 2.6234 years. Participants assert that no isotopes of Promethium are stable and emphasize that altering nuclear properties chemically is impossible. The conversation also touches on speculative ideas, such as those proposed by Ray Kurzweil regarding femtotech's potential to create new elements. Ultimately, the consensus is that achieving a stable isotope of Promethium is beyond current scientific capabilities.

PREREQUISITES
  • Understanding of nuclear physics and isotopes
  • Familiarity with Promethium isotopes, particularly Promethium-147
  • Knowledge of half-life concepts in radioactive decay
  • Awareness of theoretical chemistry and speculative technologies like femtotech
NEXT STEPS
  • Research the properties and applications of Promethium-147
  • Explore the principles of nuclear stability and isotopic decay
  • Investigate the implications of femtotechnology in modern chemistry
  • Study the limitations of current nuclear physics in creating stable isotopes
USEFUL FOR

This discussion is beneficial for nuclear physicists, theoretical chemists, and anyone interested in the frontiers of isotopic research and speculative technologies.

TL;DR
Discussing theoretical chemistry and what would it take to make artificial Promethium
Say one was to create an artificial stable isotope of Promethium as it has predicted applicable properties. What would it’s number have to be? I know Promethium-147 is semi-stable.

No isotope of promethium is stable.

I’m aware. I was asking how; if they could make an artificial one. If it’s completely impossible fine; but I was thinking speculatively. Ray Kurzweil often said femtotech could create a new periodic table.

I know Promethium-147 is semi-stable.
There is nothing that one could do 'chemically' to change the nuclear properties of a nucleus.

I would not consider 147Pm with a half-life of 2.6234 y as being "semi-stable", nor 146Pm (half life = 5.53 y), nor 145Pm (half life = 17.7(4) y).

As V50 indicated, there are no stable isotopes of Pm.

Nature would have to change its Physics, which is beyond the realm of humanity.
