Why electrons do not exist in nucleus ?
Because after finding speed of electron is more than light and this is not possible
Because nucleus contains protons nd neutrons nd provide necessery centripetal force to electrons to recolve around it
The attractive force between proton and electron is lesser than centrifugal force
Same ans of Prashant
Due to Heisenberg uncertainty principle
Proton in the nucleus repel electron
Electron and proton cannot stay together
Proton are having more mass as compared to electron which is found to be in nucleus from alpha ray scattering experiment
Due to uncertainity principle . radius of nucleus is 10 to power -15 m and radius of electron is 10 to power -10 .so it would be not possible for an electron to be present in nucleus of an atom.
Bcaz the potential energy isn't min there so electron tends to come out of it .
Also according to bohr electron orbit only in those energy levels where it's angular momentum is equal to integral multiple of nh/2pi otherwise it radiate energy and system will collapse
Baba Ji ka thullu
Speed is more than speed of light then come out of nucleus
