Why do the electrons in an atom NOT fall into the nucleus of the atom and collapse the atom?
Nonsense comparing the electrons behavior to the movement of planets or sattelites in orbit. The Earth is receiving a gravitational force from the Sun due to the distortion in the space-time fabric and believe or not Earth is falling towards the Sun. But every-time it falls say X units, it is also departing from the Sun X units cuz it also has an vertical velocity (vertical to the normal of the sun). This vetical velocity keeping Earth departed from the Sun and the velocity caused by gravitational pull is in balance so it is orbiting. In the electrons case it is not even certain that the electrons are in orbit. And the question why electrons don't fall in nucleus is being tried to be expalined in terms uncertainty principle of quantum theory which is beyond the scope of this page... You can search for this principles for further information.

The movement of electrons around a nucleus couldn't be further from the analogy of orbiting planets around a star. People use this to roughly explain the atomic structure, but it is very wrong.
Electrons occupy a space around the atom at very precise distances from their nucleuses. They move around in this space so fast that it looks like a shell or a shape. the more electrons around a nucleus, the more complex this shape if you will.
Electrons don't move anything like macroscopic objects. they disappear and reappear, even being in more than one place at once, or being in several places at once. Heisenberg describes their motion as uncertain. When the position of an electron is known its momentum is not and vice versa. They cannot be measured basically.
This is a long and complex discussion but to answer your question, Electrons do not orbit or revolve ..... (they have a property called spin but that's a different story!) They simply occupy a space around a nucleus that on their scale a vast distance from the nucleus.
you can maybe search to find different atomic shapes created by their electrons, some are spherical like, some are Taurus shaped. Weird.
I hope this helps a little.
What else can I help you with?
What are the three basic parts of an atom and where are they found?
Protons and neutrons are found in the center of the atom in a core called the nucleus. Electrons are found in a cloud that continually moves around the nucleus
What is givin off when electrons in an atom fall to a lower orbit?
Energy (in the form of photons) is given off when electrons in an atom fall to a lower energy level.
Who said electrons have fixed amount of energy?
Niels Bohr proposed that electrons are arranged in concentric circular paths or orbits around the nucleus. Electrons in a particular path have a fixed energy, thus they do not lose energy and fall into the nucleus. Experiments were base on the hydrogen atom. Results did not hold true for other atoms.
Mention two defects in Rutherford atomic model?
according to classical theory, electrons being the charged particles should release or emit energy continuously and they should ultimately fall into the nucleus. if the electrons emit energy continuously, they should form a continuous spectrum but in fact, line spectrum was observed.
Do electrons orbit around the nucleus because there is an electrical charge between electrons and protons?
This is essentially correct. The electrons and protons have equal but opposite charges, and the fundamental law of electrostatics is that opposite charges attract and like charges repel. The positive charge on the nucleus attracts and "holds" the electrons in orbit about the nucleus. It is electromagnetics that holds the electrons in orbit about that nucleus. Answer2: The attraction of the positive nucleus attracts the electrons to the nucleus by a centripetal force vp/r where v= Z alpha c. The electrons exeert a centrifugal force cDEL.P = -cp/r cos(P). When the orbit is stable the centripetal force equals the centrifugal force vp/r = cp/r cos(P) and the electrons do not fall into the nucleus. The balance gives v/c = cos(P), the redshift. This is the result of the Quaternion Energy W = -vh/r + cP, the atom has a scalar energy -vh/r and a vector energy cmV=cP, the Momentum vector energy. The mystery of what holds the electron from falling into the nucleus is the Divergence of the vector energy. Physics has come to grips with the fact that energy is a Quaternion quantity with a vector energy and the Divergence of the vector energy creates the centrifugal force, the cosmological constant force and the Dark Energy.

What are drawbacks of Rutherford's atom model?
Rutherford explained that all the positive charge was concentrated at the centre and the electrons revolved around it. But this theory was discarded as a charged particle undergoing circular motion would accelerate and an accelerating particle looses energy. Hence, the electron would fall into the nucleus and the atom will collapse. But this doesn't happen. So, Rutherford's model of atom was discarded.
What did the Bohr model address the problem of?
why electrons didn't fall into the positive nucleus how so many positive charges could be crowded into such a small space in the nucleus how so much energy could be released from an atom
What is the force thea holds an electron to an atom?
The electromagnetic force (protons are positive and electrons are negative, so they attract), which is manifested into Coulomb's force of attraction. The reason that electrons will not fall into the nucleus is due to the electron's energy; it is moving fast enough to not collide with the nucleus.
What are the shortcomings of Rutherford's atomic theory?
Rutherford explained that all the positive charge was concentrated at the centre and the electrons revolved around it. But this theory was discarded as a charged particle undergoing circular motion would accelerate and an accelerating particle looses energy. Hence, the electron would fall into the nucleus and the atom will collapse. But this doesn't happen. So, Rutherford's model of atom was discarded.
Problems with Rutherford model?
In Rutherford's model of the atom the electrons had a circular motion around the nucleus. By the laws of physics, if something is going in a circular motion then it must be accelerating and a particle that accelerates is losing energy. This means that the electrons that are revolving around the nucleus would eventually fall into the nucleus. Nucleus would eventually collapse. This does not happen therefore the Rutherford model was put aside.
What is givin off when electrons in an atom fall to a lower orbit?
Energy (in the form of photons) is given off when electrons in an atom fall to a lower energy level.
What holds electrons in their shells?
The electrons "orbit" the nucleus of an atom. They do so because they are attracted to the positive charge of the protons inside the nucleus. They do not usually leave the atom because of this attraction, and do not usually fall into the nucleus because they are moving.
What happens when an atom has no more electrons?
it would fall apart.
Why are electrons attracted to the center of the atom?
Electrons are attracted to the center of the atom, called the nucleus, due to the positively charged protons in the nucleus. Opposite charges attract, so the negatively charged electrons are drawn towards the positively charged nucleus. This attraction keeps the electrons orbiting the nucleus in defined energy levels.
Why don't all the electrons in an atom fall to the lowest energy level?
Electrons in an atom do not all fall to the lowest energy level because of the Pauli Exclusion Principle, which states that no two electrons in an atom can have the same set of quantum numbers. This means that electrons must occupy different energy levels within an atom, leading to a distribution of electrons across multiple energy levels.
When electrons gain additional energy do they move farther away from the nucleus?
In general, electrons farther from the nucleus will have more energy than electrons closer in. These "outer" electrons are said to be in higher Fermi energy levels, and they have more kinetic energy than the electrons in lower orbitals. Consider that electrons give up energy to "fall into" closer orbitals, and they will, in general, have less energy than the outer electrons. A consequence of the idea that there is less energy binding outer electrons to that nucleus is that it takes less energy to remove that outer electron from an atom. These are the so called ionization energies of the atom's electrons. And when the electron is in a higher orbital, it has a lower ionization energy. It can be removed more easily. As we attempt to remove more electrons from that atom, it takes progressively more and more energy as we move inward removing electrons.
