Question
Which of the following has the highest neutrons ratio ?
Options
A.92U235
B.8O16
C.2He4
D.26Fe56
Solution
Neutrons ratio that is 
determines the stability of nucleus. (Here, n is number of neutrons and p is protons).
Now, n = 235 - 92 = 143
p = 92
For 92U235; Neutron ratio =
= 1.55
Which is the highest no. So, 92U235; is most unstable.
