Binding energy
Binding energy refers to the minimum amount of energy required to break the nucleus or binding energy is the energy required to separate the nuclei from each other is called binding energy.
If I were to ask you how to find the mass of the nucleus, what would be your answer? The nucleus can be an atom of any element) but in reality this is not the case. To explain this, we have to understand Einstein's equation E = mc * 2, according to which mass and energy are two sides of the same coin, according to which mass can be converted into energy. Note that here the energy changes from one form to another because according to Einstein's equation there is only one form of mass energy. The "remaining mass" is released in the state of energy. That is why the actual mass of the nucleus is less than its theoretical mass. We can use Einstein's equation to calculate the amount of energy that is required to make a vacillation.
∆E = ∆mc ²
Here m∆ refers to mass defect which occurs after extraction of actual mass from theoretical mass or also called mass difference. If we know the mass defect of any atom then you can find out How much energy was released when the nuclei of this atom joined together to form the nucleus. Since mass defect is different for each atom of the element, The mass defect will be different from that of the hydrogen atom or any other element of the atom.
The point to note here is that when the nuclei come together to form the nucleus of an atom, a huge amount of energy will be released as a result. Now the question is, So obviously I have to give the same amount of energy as was released during their encounter which is called binding energy. Binding energy is called nucleons which means how much energy will be required to remove a nucleus from the nucleus .
The highest energy required for extraction is 8.7945MeV. But when it comes to total binding energy, it is iron.
If you consider, binding energy is also a good way to help us know which atom is more stable, that is, how strongly its nuclei are bound to each other and which force. This is called nuclear force. If the binding energy of an atom is high, it means that the nuclei of this nucleus are tightly bound together.
