Default List of Nuclear reactions that can take place in Universe.

I read somewhere, nuclie collide with each other to produce nuclear
reaction the same way as chemical reaction occurs.

Chemical Reaction

H+H - H2

O+O -O2

2H2 + O2 - 2H2O

Simmilarly Nuclear Reaction occur.

H1+H1 - He {fusion}

U238 - U235 {fission}

When Universe begain everything was hydrogen. Hydrogen collided with
each other to bring Helium.

Then these elements collided to bring larger elements. Like Li, B,
Carbon etc.

At even higher temprature they collide to give Iron, Aluminum & Gold.

Can someone tell me where can I get list of all such nuclear
Reactions.

Along with at what temprature these reactions take place.

And is it possible for Iron nucle to fuse together to give even higher
Elements? And where in our universe these reactions take place.

Hydrogen+Hydrogen-Helium take place in Sun. What about other
reactions?

Not on this forum, bub (alt.philosophy). And you also crossposted to
alt.atheism?

Of course not. No one knows any science here.

Then you read incorrectly.
Nuclear reactions are nothing like chemical ones.

Chemical Reaction

H+H - H2

O+O -O2

2H2 + O2 - 2H2O

Simmilarly Nuclear Reaction occur.

H1+H1 - He {fusion}

U238 - U235 {fission}

Rubbish.

Then these elements collided to bring larger elements. Like Li, B,
Carbon etc.

At even higher temprature they collide to give Iron, Aluminum & Gold.

Reactions.


Yep. A university library.

Along with at what temprature these reactions take place.

And is it possible for Iron nucle to fuse together to give even higher
Elements? And where in our universe these reactions take place.


Supernovae.

Hydrogen+Hydrogen-Helium take place in Sun. What about other
reactions?


Lithium, Carbon etc.
Can't you use google?

Not in the same why. Chemical reactions are mediated by the electromagnetic
force compare to nuclear reactions which are mediated by the weak and
strong nuclear forces.


Chemical Reaction

H+H - H2

O+O -O2

2H2 + O2 - 2H2O

Simmilarly Nuclear Reaction occur.

H1+H1 - He {fusion}

U238 - U235 {fission}

SNIP

Elements? And where in our universe these reactions take place.


No. Elements heavier than Iron are produced by endothermic neutron capture
plus a bunch of decays.
