The largest known completely stable (e.g., stable to alpha, beta, and gamma decay) nucleus is lead-208 which contains a total of 208 nucleons (126 neutrons and 82 protons).
It is certainly a rare and highly radioactive element. To say it is the "strongest" might be a bit much.
iron
osmium
a stable element is an element which have been able to complet its octect rule, i.e the electron of its outermost shell is complet, this is what is called a stable element
A stable element is any non-radioactive element. All elements before element atomic number 84 (not including 84) - Polonium (Po) are stable elements.
Fluorine
Fluorine is a stable element.yes.
Helium is a stable element.
the element is stable.
it's stable, but it is a reactive element!
argon
No its not.
