How is the energy stored in uranium?
Uranium-235 has the property of undergoing fission (splitting) when it absorbs another neutron, and this fission releases energy in the form of heat. Energy cannot be put back into the uranium, it is a one-way process which destroys the uranium nucleus and forms other lighter elements.
What two factors control the properties of a mineral?
Chemical composition and internal arrangement of atoms
Does the total number of atoms stay the same during a chemical reaction?
Indeed by the Law of Conservation of Mass, mass cannot be lost or gained through a reaction. Similarly, atoms cannot be lost, gained or somehow transformed themselves-only rearranged into different compounds. This means there are still going to be the same amount of Hydrogen atoms after a reaction as there were before.
Are atoms conserved in chemical reactions?
The same number of each type of atom (each element) still exists after a chemical reaction. They simply attach to other atoms (or detach) in various ways to form molecules (or molecules break apart into atoms).
Why can nuclei of carbon oxygen and iron be found in stars?
Nuclear fusion between nuclei of smaller atoms forms the nuclei of larger atoms and releases energy.
Why doesn't an atoms identity change during a chemical change?
The energy involved in chemical reactions is not so strong to affect the identity of atoms; only nuclear reactions can modify an atom.
How else are nuclear reactions unlike chemical reactions?
In nuclear reactions the atom itself changes while molecules and/or structural organisation of atoms do in chemical and physical changes.
Are atoms created or distroyed in a chemical?
i think that in nuclear reactions but in normal reaction not created and destroyedAdded:No, never created or destroyed. Only in nuclear reactions some atoms may change in other atoms (by decay or fusion) but still not (totally) distroyed.
Do chemical reactions produce new atoms?
No, only nuclear reactions can.
Is fusion a mechanical or chemical or nuclear?
Fusion of smaller atoms to form larger atome is a nuclear change. Ex: 4 hydrogen atoms FUSE to form an atom of helium through a compeles set of nuclear reactions.

What is the process where in a nuclear reactions of atom are being transformed into atoms of simple element?
nuclear fission
Do atoms break in reactants?
No. Atoms never, ever break in chemical reactions. Molecules break if you want to see atoms break, look up nuclear reactions
What involves the use of the nuclei of atoms?
You think probable to nuclear reactions.
Is is possible to convert atoms of one element into atoms of another?
According to Dalton's atomic theory chemical reactions occur when atoms are separated, joined, or rearranged. Atoms of one element, however, are never changed into atoms of another element as a result of a chemical reaction (it is possible only during nuclear reactions and radioactive disintegration).
How are chemical potential energy and nuclear energy different?
Chemical energy arises through reactions between atoms of different materials, whilst nuclear energy arises through reactions in the nucleus of the atoms. In chemical reactions the nuclei are not affected or changed.
Why is uranium a non- renewable fuel?
Because uranium atoms disappear by nuclear fission an other nuclear reactions in nuclear reactors.
