I guess uranium is used because the attoms Split , what about regualar atoms , if they could be spit?

by some means , you would get the same force of explosion ?I guess uranium is used because the attoms Split , what about regualar atoms , if they could be spit?
Ah, you have some misconceptions here.





Atoms in wood or any other matter do not burn in fire. Fire, rapid oxidation, occurs at the molecular level, not at the atomic level.





For example, when wood is burned (oxidized), its carbon combines with oxygen to form carbon dioxide and/or carbon monoxide depending on how much oxygen there is in the surrounding air.





In symbols that's C + O2 -%26gt; CO2, and that's at the molecular level as neither the carbon atom C nor the oxygen atom O is altered. That is the atoms remain the same, they just combine at the molecular level when oxidation occurs.





But when we split atoms, we are creating different lighter atoms than the ones we started with before the splitting. It is easier to split the bigger (heavier) atoms than the lighter ones because the bigger ones are on the brink of splitting on their own. That results because the proton repulsion that would split them apart in the bigger ones almost overshadows the attractive weak and strong forces that pull them together. Although, in theory, we can split the lighter atoms, it would take a heck of of lot more energy to do that and would be inordinately expensive to do.





We can get energy from splitting atoms because of e = mc^2, which is Einstein's famous energy equivalence equation. Turns out that the total mass of a heavy atom M %26gt; SUM(m) is greater than the sum of the lighter atom masses m that result from the split. Which means there is more mass before the split than after. In math talk, that's M - SUM(m) = dm %26gt; 0 where dm is called the mass deficit. So the energy we get from that split is e = dm c^2 where the deficit was converted into energy e.





Notice we do not add heat (fire) to this spitting thing. We split a heavy atom by bombarding it with neutrons and when an atom captures one of these, its energy level is raised and that causes the atom to split. So the bottom line, if you heated a heavy element, like plutonium Pu, hot enough, that would not cause its atoms to split. But what it would do is oxidize that atom and create plutonium oxide, a molecule, which is extremely toxic and radioactive.I guess uranium is used because the attoms Split , what about regualar atoms , if they could be spit?
lol, wood is not an element, it is an organic, made of complex chains of elements called molecules. These molecules make up more complex parts, like DNA, and cell walls, and fiber, and cellulose, that all make up the tree.





in and forest fire, the wood burns, but atomically, nothing changes - burning wood is a chemical reaction to create fire.





Fire is basically a chemical reaction with fuel. Oxygen + fuel (wood) + heat = flame + CO2 and other byproducts (mainly carbon based)





As for your last detail - yes, if you got something hot enough, atoms may split, but not explode. But then your talking about temperatures like that on the surface of the sun.
Certainly other atoms can be split. The advantage of uranium (and plutonium) is that when it splits, it gives off neutrons that can force other uranium atoms to split leading to a chain reaction that releases energy. To split most atoms, energy must be added to the atoms usually by a particle accelerator. This type of splitting will not result in an explosion.
I don't think so because most other atoms are very stable. It would probably take MORE energy to split them then you would get out of the reaction.
