We can explain this by heisenberg's uncertainty principle .
Formula = Δx . Δp > h/4π
Δx . m . Δv> h/4π
Δv> h/4π·Δx·m
Now 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 get
Δv > _______x10^11
that is an electron cannot have velocity greater than the velocity of light.
hence it cannot exist in nucleus
