In which location would a free neutron from a decaying u-235 atom be most likely to cause another atom to split?

a. in a sample of naturally occurring uranium

b. in a sample of enriched uranium

c. in a sample of rock or soil

d. in the sun’s core

e. in a distant star

The answer is; B

This is because enriched uranium has minimal impurities. Therefore, the uranium-235 atoms are concentrates together and the chances that the neutron will bombard another U-235 atom in the vicinity is high. This increases the rate of radioactive a chain reaction. This is why enriched uranium is used to make  nuclear bombs and nuclear reactors.

B. In a sample of enriched uranium
