Difference between binding and bonding energy

[anonymous24]

Hello,
I am not sure whether it is the right place to post this but I am a bit confused about the bonding in chemistry and the binding energy in physics. From what I have read, in a nuclear fusion reaction, the released energy due to mass defect is converted to the kinetic energy of the product particles. However, in chemistry, the process is exothermic when bonds are formed, is it a similar process? Also, why would the energy released as heat instead of the kinetic energy of the product molecules? Thank you in advance.

It is very similar.

Only if two or more particles are created, otherwise it happens via the emission of radiation.
The same applies to chemical bonds.

Chemical binding energies are much smaller, so the motion of particles or the emission of radiation is directly close to thermal motion/radiation, whereas fusion processes produce very fast particles or high-energetic radiation.

Thank you for your response. I do understand the first part, but I'm not sure what do you mean by "thermal motion", could you please elaborate on it. thank you!

Motion of particles due the temperature. I don't understand what is unclear.

Thank you, I was just a bit confused but I am clear now. :)
