How do I know what reaction is this? Is there any calculations to do? Or I have to look up for visual signs in the reaction?

    Good morning UnusualKamino2636.

    Welcome in the Zone d'entraide!

    The main difference between fission and fusion is that fission is the splitting of an atom into two or more smaller ones while fusion is the fusing of two or more smaller atoms into a larger one.

    When you look at this nuclear equation, you see that at least one reactant nucleus is bigger than any of the products nuclei. That is typical of a fission reaction. In a fission reaction, big nuclei become smaller nuclei. Fission occurs when a larger atom split into two or more smaller (lighter) atoms. A larger means containing more particles.

    Here's a nice website containing information about fission and fusion :

    Transmutation is a process that involves a change in the nucleus of an atom. When the number of protons in the nucleus of an atom changes, the identity of that atom changes as it is turned into another element. In this process, you have one isotope as a reactant and one isotope as a product.

    Hoping these informations helped you to make différences between these processes.

    This Alloprof webpage explains nuclear fission and fusion:

    Thank you for making Alloprof your confidence partner. Have a nice day.
