What else can I help you with?
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).
How does an electron that was transferred to the shell of another atom stay there without another proton in the nucleus attracting it?
A common misconception is that proton 1 in the nucleus attracts electron 1 in the orbitals, proton 2 attracts electron 2, etc. This is very, very wrong: every proton attracts every electron all at once. Further electrons, as in beyond the neutral charge, are attracted in the same way as all other electrons, and held subject to a) repulsion and shielding from other electrons and b) remaing gaps in orbitals to fit them.
What were rutherford's and Thomson's key discoveries about the atom?
Rutherford's key discovery was that the atom has a small, positively charged nucleus and is mostly empty space. Thomson discovered the electron and proposed the "plum pudding" model of the atom, in which electrons were embedded in a positively charged sphere.
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.
What fills the space between the atomic nucleus and the electron cloud?
The space between the atomic nucleus and the electron cloud is primarily filled with empty space. This empty space allows for electrons to move about freely and occupy different energy levels within the electron cloud.
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).

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 is the attraction called that forms ionic bonds?
The attraction is called an electrostatic attraction. It occurs between two oppositely charged ions, with one ion donating an electron (cation) and the other ion accepting an electron (anion) to form a stable ionic bond.
What part of an atom flows as electricity?
the electron, though any charged particle can create a flowing current.
What were rutherford's and Thomson's key discoveries about the atom?
Rutherford's key discovery was that the atom has a small, positively charged nucleus and is mostly empty space. Thomson discovered the electron and proposed the "plum pudding" model of the atom, in which electrons were embedded in a positively charged sphere.
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
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.
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).

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.
Are the electrons found inside the nucleus?
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.
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.
