    # It is said that the Binding energy per nucleon of Uranium-235 is about 7.6 MeV. In spite of its high Binding energy per nucleon, why is it unstable?

    becuase it has to much energy in it, the less energy the more stable it becomes. Like if you have a ball on a hill, it have alot of energy, but it will automaticly go to a lower energy level (lower height) until it comes to either the lowest possible energy or something that prevents it from going lower

    now the real question. if it's still that instable, how did it exist in the first place. AND it isn't instable actually.. for an isotope it's quite stable.. Helium 3 is unstable, just 10 seconds for halftime.

    It is NOT the energy the atom contains what makes it unstable. it is the number of neutrons. If the number of neutrons is not a stable one it'll fall apart until the number of neutrons will make it stable again.

    there are several tables that show the exact numbers.

    you'll have to google yourself or someone else should be so kind to post one
    Growing up, i marveled at star-trek's science, and ignored the perfect society. Now, i try to ignore their science, and marvel at the society.

    Imagine, being able to create matter out of thin air, and not coming up with using drones for boarding hostile ships. Or using drones to defend your own ship. Heck, using drones to block energy attacks, counterattack or for surveillance. Unless, of course, they are nano-machines in your blood, which is a billion times more complex..

    it is the energy, having to many neutrons is making it having to much energy in it, but proton is also giving to much energy to it all. after a certain eleent (thiunk its lead) no matter how many neutrons its still unstable

    isn't this why nuclear fission works, firing another neutron takes it over the edge and causes it to split, thats the reasons why its used for reactors and bombs

    think thats right

    yes it is, helium 3 is stable, but you are not a professor
    He is stable with 1 neutron
    from wikipedia

    what was the story then about the radioactive gass that can be mined on the moon?? Thought it was helium 3..

    maybe some gas is radioactive there, but it is helium 3 on the moon that is desireble for fusion
