Question

The atomic nucleus contains two subatomic particles, the proton and the neutron. Atoms of different elements have different numbers of protons and neutrons. Indicate which element listed is the most unstable and likely to undergo nuclear decay.

Answer 1

Titrium, C-14 are the elements unstalbe which i know

Answer 2

Alright since you haven't updated your question, I guess I'll just go ahead and tell you the method...


The concept is that for elements with atomic number less than 40, neutron to proton ratio should be greater than 1, for stability.. And for elements with Z > 40, n/p ratio must be less than 1..


Hope it helps...
