Why electrons are not present in the nucleus?? |
| Answer» We can explain this by heisenberg\'s uncertainty principle .Formula = Δx . Δp > h/4πΔx . m . Δv> h/4πΔv> h/4π·Δx·mNow if electron is in the nucleus then Δx= 10^-15m (size of nucleus){tex}m= 9.1 × 10^-31kg, h= 6.626× 10^-34{/tex}If we substitute all the values and just observe the power on ten we getΔv > _______x10^11that is an electron cannot have velocity greater than the velocity of light.hence it cannot exist in nucleus | |
