What is Fission and Fusion?
Submitted by: AdministratorFission: The breaking down of a Nucleus (not atom) into
smaller nuclei. It is usually induced by a neutron.
For example, a Helium nucleus (called alpha particle) is
divided into two 4He(+2) --> 2H(+1) + 2H(+1)
A lot of enery is released in the process.
Fusion: This happens when two nuclei combines to form a
larger nuclei. Huge amount of enery is needed to start
this. Because its not easy to bring two positively charged
nuclei closer.
When they combine, a huge amount of energy is released.
This usually happens in the stars.
The enery required to start the fusion comes from the
gravitational force between the particles.
