Why is an electron not present within a nucleus?
When a nucleus is formed, the nucleons involved, that is, the protons and neutrons that are going to be forming the nucleus, are "squeezed" together in the fusion reaction. During this reaction, the stong interaction or strong nuclear force mediates the conversion of some of the mass of each proton and neutron that is going to make up the new nucleus into nuclear binding energy. The binding energy, or nuclear glue, is created from a bit of the mass of each nucleon involved through what is called mass deficit. If any electrons are present in the vicinity of the fusion reaction, they are "locked out" of the reaction by the strong interaction. The electron will not be permitted to become involved in the fusion reaction because it does not have the "right stuff" to participate. That is why no electrons can be in a nucleus. Note that in some kinds of nuclear decay called beta minus decay, an electron is created within the nuclues, and it is quickly ejected. The electron did not exist in that nucleus, but was created through the mediation of the weak interaction or weak nuclear force. A neutron was converted into a proton and an electron and an antineutrino, and then the electron was kicked out of the nucleus.
Though the electron itself is not present in the nucleus of an atom, the elementary particles that make up the electron are present inside the neutron. In other words, a neutron is made up of an electron and a proton. How do we know this? Because when a neutron decays, it slowly decays into a proton and an electron. It's a cycle.
Though the nucleus gives out electrons as beta particles in the phenomenon of beta decay, nucleus does not have electron within. Then how could an electron come out? This is actually an interesting question. A neutron is capable of decaying into a proton and an electron along with a formation of anti neutrino. This electron comes out as beta particle.
While it is useful to visualize an Electron orbiting an atomic nucleus like a moon orbiting a planet. It is more realistic to think of the Electron as a standing wave (with a fixed number of wave crests and troughs) surrounding the nucleus. The electromagnetic force holds the Electron and nucleus together. The Electron holds a negative electrical charge and the nucleus a positive electrical charge and the two attract one another. Therefore for each…
Electrons are located outside the nucleus revolving around. These electrons may be named as Chemistry electrons. But when neutron within the nucleus decay, then proton and electron are produced. This electron was not already there in the nucleus. But only due to decay of neutron electron comes out. This electron may be named as Physics electron. This electron comes out at very speed and this is sensed as beta particle, named by Henry Becquerel.

i am telling on ly two characteristics for each atom component- electron-it contains an unit negative charge and actively takes part in all the atomic reactions. proton-it contains the same charge as the electron does but it is positively charged.protons are present inside the nucleus. neutron-it is neutrally charged particleand present inside the nucleus.
Electrons are attracted to the positive charge on the nucleus. The further an electron is found from the nucleus of an atom, the lower the force of attraction between it and the nucleus. Therefore an electron far away from the nucleus (like a valence electron) will have less of an attraction to the nucleus than one close to it. A lower attraction to the nucleus translates into the fact that less energy would then be…
The electromagnetic force that acts between the nucleus and the electron keep it in orbit about that nucleus. The nucleus is positive, and the electron is negative. In the world of electric charges, like charges repel and opposite charges attract. The electron is attracted to the nucleus where the protons, which are positive, hang out.
In an s orbit the probability of finding an electron a particular distance from the nucleus does not depend on?
When you add energy to an electron (which happens when an electron absorbs a photon) the energy takes the form of an increased distance from the nucleus, since there is an attraction between the electron and the nucleus, and energy can be released (in the form of a photon) when an electron moves closer to the nucleus. In a ground state, the electron is at a normal distance from the nucleus.
