The water drop model of an atom’s nucleus explains it well. First, two protons don’t want to be right next to each other due to electric repulsion. But if they get very close, there’s an extremely short range force that will hold them together, bu

In reality, U-235 releases the 3 neutrons (it has plenty to spare anyway), and so we need to work hard to acquire the rather rare U-235 in order to harvest the power of chain reactions. U_238 has a natural abundance of 99.3% and U_235has an abundance of 0.7%. It is the rarer U_235 that is needed for nuclear reactors.

Naturally occurring Uranium is about 99.3% U-238, and about 0.7% U-235. U--235 is the only naturally occurring isotope (in large quantities) present on Earth that is fissile.
