How is the Energy Limit of a Uranium Atom Determined?

AI Thread Summary
When an atom is split, a finite amount of uranium does indeed produce a finite amount of energy, determined by the mass difference before and after fission, calculated using E=mc². The energy contained in a single uranium atom can also be derived from its mass, but this does not equate to the energy released during fission. The discussion emphasizes that the law of conservation of energy remains intact, suggesting that the total energy in the universe is constant. Questions arise regarding potential changes in this understanding due to concepts like black holes and dark matter, but no definitive updates have been established. Overall, the principles of energy conservation continue to hold true in current scientific discourse.

Could anyone with some expertise answer these questions for me?

When an atom is split, does a finite amount of uranium produce a finite amount of energy?

What determines how much energy a uranium atom might contain?

Of course a finite amount of Uranium corresponds to a finite amount of energy, what else could it be?

To find the amount of energy released in fission, take the difference in masses of the resulting atoms and the original atom of U, apply E= mc2.

As for how much "energy" a Uranium atom might contain, simply apply E= mc2 to the mass of a single atom of U. Understand that this is not the amount of energy released in a fission reaction (see above).

Nothing else that I can think of, as far as I know the law of conservation of energy has never been broken. I wish the answer to something farther ahead, that’s where my questions end.:smile:

Then the energy released is always directly proportional to the mass of its atom. This equation to be correct then, assumes that there is a equality on both sides of the equation.

I have been listening to the Richard Feynman lectures trying to understand some of these things.

Is it correct to assume then that, there is always the same amount of E in the universe? Has there been any changes in knowledge, on the law of conservation of energy, with what we know now about theoretical black holes or dark matter?
 
So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
