Why an electron does not enter the nucleus even though they are oppositely charged?

At a very rough guess the same reason we don't enter the sun even though gravity pulls us:
The speed and direction of the electron is maintained while the opposite change has a strong enough magnetic effect to stop it from escaping.

Is the electron cloud outside the nucleus?
Yes, though interestingly the probability density for finding an s orbital electron is actually higher in the nucleus than anywhere else (this assumes the nucleus and electron are point masses; in reality, they aren't, so it doesn't quite work out that way in the real world).
Does an atom has a densely packed nucleus that is positively charged if yes then why do you hear that nucleus has no charge its neutral?
A nucleus is densely pack and positively charged because it is made up of protons and neutrons. But the entire atom is not charged (unless it is an ion) because the number of protons is equal to the number of electrons not in the nucleus. The electrons are actually really far away from the nucleus, so the charges are kept very separate in the atom, though all together the atom is neutral.
Why is the region around the nucleus called the electron cloud?
It is called so because that region is where the electron whiz around in their orbits, creating a sort of 'cloud'. Interesting question though.
What fills the space between the atomic nucleus and the electron cloud?
To say there is nothing there is simillar to saying water has no taste. There is something there, though we have yet to observe or define it.
How does an ion become a cation?
any atom lose one electron or more become positive ion ( Cation ) Dont really get your question:( BY definition, an atom that has lost or gained an electron meaning its a charged particle. A cation is an atom that has lost electrons to form a positively charged atom meaning that a cation is an ion. However, an anion also falls under the definition of an ion ( An anion is an atom that has gained an electron to form a negatively charged particle) In that case, it will need to lose electrons to form a cation(positively charged particle.) Not sure if you are referring to that though hope that helps:DD

Why energy is released during the addition of first electron into oxygen atom?
Even though an oxygen atom is electrically neutral, since it has equal numbers of protons and electrons, it can still act as though it is positively charged, because the electrons are very mobile and they arrange themselves in a way that maximizes their connection to the nucleus while minimizing their connection to other electrons, which repel them. So when an oxygen atom adds an electron, that electron is attracted by the positive nucleus more than it is repelled by the negative electrons orbiting the nucleus. The separation between the electron and the nucleus is a form of potential energy, just as you gain potential energy by raising an object in a gravitational field. As the electron falls toward the nucleus, potential energy is converted into other energy, such as heat or light.
What moves around the nucleus of an atom?
Electrons, which are a type of fermion, orbit the nucleus of atoms. Remember, though, that they do not actually orbit or "move around" the nucleus, but instead are in a superposition of states, which we usually describe as an electron density, or the probability of locating an electron at a certain distance and time.
Why does the compound formed by an ionic bond have a neutral charge even though the ions that bond are charged?
Because if its valence electron has 3 protons on the outer shell, then it'll stay charged even though the ions that bond are charged.
What part of an atom flows as electricity?
the electron, though any charged particle can create a flowing current.
Can electrons be found in the nucleus of an atom?
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.
What is called valency of an electron?
In fact an electron has no valency, though it is equal to a -1 (minus one) charged anion like Cl-, having a valency of -1
Electrons are found the nucleus?
Yes, though interestingly the probability density for finding an s orbital electron is actually higher in the nucleus than anywhere else (this assumes the nucleus and electron are point masses; in reality, they aren't, so it doesn't quite work out that way in the real world).
Are the electrons found inside the nucleus?
Although there exists a non-zero probability for an electron to be within the nucleus, the greatest probability is for them to be found somewhere outside there. The average (more precisely, the expectation value of the) distance between an electron and the nucleus is represented by the different periods of the periodic table. With an increasing period number comes an increasing average distance.

Is all of the mass in an atom in the nucleas?
The mass of an atom is mostly in the nucleus. Though electrons that orbit the nucleus also have mass, their masses are so small (each electron is 1/1823th the mass of a proton), the mass of any atom would be 99.9% in the nucleus.
