Why are Technetium and Promethium radioactive?
« on: May 06, 2013, 11:40:52 AM »
Hi,
I always wondered about this strange fact, considering the non-radioactive neighbour elements. Do you know why exactly these two are radioactive? Or is it just coincidence? Or unexplicable?
Thanks for any answers!

Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.
