why nuclear radiations occur in atoms with large nucleus?Is it the weakening of residual strong force?
If so why it gets weak ?
If so why it gets weak ?
It does not get weak, but the repulsion between all those protons grows quicker than the binding due to the residual strong force*. Therefore, as a general tendency, very big nuclei are more likely to decay in some way.abi.ayan said:why nuclear radiations occur in atoms with large nucleus?Is it the weakening of residual strong force?

abi.ayan said:But in tritium atom there is only one proton.Hence there will be no repulsion.So why do it radiate??
The part you quoted was about alpha radiation - something you mainly find at big nuclei.abi.ayan said:But in tritium atom there is only one proton.Hence there will be no repulsion.So why do it radiate??
Nuclear radiations occur in atoms with large nucleus because of the instability of the nucleus. As the nucleus becomes larger, the forces holding it together become weaker, making it more likely to undergo radioactive decay.
Large nuclei become unstable due to the imbalance between the strong nuclear force, which holds the nucleus together, and the electrostatic repulsion between protons, which tries to push the nucleus apart. This imbalance becomes more pronounced as the number of protons in the nucleus increases, making it more likely to undergo radioactive decay.
The release of radiation from a large nucleus is caused by the process of radioactive decay, where unstable nuclei break down into more stable forms. This decay process releases energy in the form of radiation, such as alpha, beta, or gamma particles.
No, not all atoms with large nuclei are radioactive. The stability of a nucleus depends on the balance between the strong nuclear force and electrostatic repulsion. Some large nuclei are stable and do not undergo radioactive decay, while others are unstable and release radiation.
Yes, nuclear radiations can be harmful if exposure is excessive. High levels of radiation can damage cells and tissues in the body and lead to health problems, such as cancer. However, low levels of radiation are constantly present in our environment and are not harmful to our health.
