Is electrons present in side the nucleus or not if yes how
If not how bita rays emitting from nucleus?
Electrons are not present inside the nucleus of the atom. The nucleus is made of proton and neutrons whereas the electrons revolve around the nucleus inside the atom.
For the formation of beta rays, it emerges from the nucleus. This radiation happens in the nucleus when the neutrons are more compared to protons in the nucleus (remember: protons and neutrons are of equal numbers inside the nucleus in a standard atom). So the extra neutrons present in the nucleus turns itself into a proton and electron. So, that's how you end up having electrons in the nucleus. Since electrons does not belong to the nucleus they emerge out as beta radiation.
read lessNo, electrons are not present inside the nucleus as positive and negative charge combination makes atom electrically unstable. But in case of beta ray emission,electrons are emitted only when nucleus of an atom undergo Radioactive decay. It was emitted by neutron i.e., β- decay. Don't mix atom structural arrangement and radioactive decay phenomenon both are entirely different.

Bita rays emits when no or the ration of neutrons are too high as compared to proton inside the nucleus so at that time some of neutrons changes to electron or a psitron as positrons are positively charged they can remain inside the nucleus but electrons can not remain inside the nucleus thus they are emitted from nucleus at a high speed . So its actually the neutrons that accumulate negative charge on them and get emitted at high speed from the nucleus this also shows that electron can not reside inside the nucleus.
