In order for nuclear fusion to occur, atomic nuclei must overcome the Coulomb barrier by colliding violently.
What is nuclear fusion?
- A reaction known as nuclear fusion occurs when two or more atomic nuclei fuse to create new atomic and subatomic particles (neutrons or protons).
- Energy is released or absorbed depending on how much mass there is between the reactants and products.
- The difference in nuclear binding energy between the atomic nuclei before and after the reaction is what causes this mass difference.
What is Atomic nucleus?
- On the basis of the 1909 Geiger-Marsden gold foil experiment, Ernest Rutherford identified the atomic nucleus in 1911, which is the compact, dense region made up of protons and neutrons at the heart of an atom.
- Dmitri Ivanenko and Werner Heisenberg immediately created models for a nucleus made of protons and neutrons after the neutron was discovered in 1932.
- A positively charged nucleus and a cloud of negatively charged electrons that are held together by electrostatic force make up an atom.
