details of electrons anyone?

Question

What will happen if electrons do not revolve round the nucleas?Where does the energy in spinning electrons come from?

Answer 1

The correct way to think of an electron around an atomic nucleus is to think of an electrostatic "potential well". The electron is trapped inside the well, so there is no need for the electron to revolve or spin around the nucleus. However, the electron does have angular momentum, but this is not the classical angular momentum you are used to (because electrons are point particles and do not have physical extension like a ball rotating about its center of mass). For an electron, its angular momentum are quantized, and also include a "spin" component that has nothing to do with "spinning" around an axis, but does have something to do with orientation. Also, in terms of picturing the electron around the atomic nucleus, it is useful to think of it as a cloud, smeared and surrounding the nucleus. But what kind of cloud is it? This obviously is not a cloud of gas, rather the cloud metaphor is to denote the fact that we do NOT know where the electron is at any given moment. This has to do with Hisenberg's Uncertainty Priniple. If we knew exactly where it is, then we would have no idea what momentum it has, which implies that the electron would gain energy and escape the nucleus.

So to answer your question, "what will happen if electrons do not revolve around the nucleus?" The electron may escape the nucleus if it receives the right amount of energy. For example, a photon or light of a certain frequency can collide with the electron and impart its energy to the electron and thus causes the electron to escape the nucleus. This is called the Photo-Electric Effect (as discovered by Einsteinand winning him a Nobel Prize).

"Where does the energy in spinning electrons come from?" The electrons trapped inside the potential well of an atomic nucleus must be in certain quantum states that correspond to a certain amount of energy. This corresponds to the binding energy of the electron to the nucleus, which is also the energy required in order for the electron to escape the nucleus.

As a side note, the most "accepted" view of an electron among quantum physicists is that the electron is a "wave packet". The wave packet is a mathematical representation of the probability of finding the electron at some position (x,y,z) and at time, t.

Answer 2

Electrons are negatively charged particles that are present in an atom to balance the positive charge of the nucleus to make an atom's charge neutral. Electrons are bound to the nucleus by its positive charge and revolve around it in specific orbits. It's just like planets revolving around the sun held by the sun's gravitational force. If they don't revolve, then they would detach and ionize every atom. It would become impossible to do anything without being electrocuted, as electricity is flow of electrons. Electrons would fly everywhere without anything to keep them bound and create chaos. Electrons in an atom revolve in different orbits around the nucleus. Electrons on orbits closer to the nucleus' power have more energy as they need more power to keep away from joining the nucleus. On no account will an electron ever combine with the nucleus. The electrons in further orbits need less energy as they are further away from the influence of the nucleus. The energy is just there. The electrons want to break out from the influence of the nucleus but the nucleus keeps pulling it back. This exchange of forces results in the revolving of the electron in a fixed orbit. Neither will it join the nucleus, nor will it detach from an atom.

Answer 3

Quantum Physicists now realize that electrons do not so much revolve but they are more like clouds. Also electrons are more like a angle that exists on the atomic level of space time. This has brought about the theory that because it is the same angle, its all the same electron. Infact the plural "electrons" does not exist. I have wrote this many times before but it is also believed that electrons move backwards in time while positrons (their antimatter counterpart) moves forwards. If electron clouds were not sticking to a atoms nucleus you would have a uncharged atom with holes, and chances are the electron would be attracted
to the hole and create the nessesary angle within the atom.

Answer 4

According to the earlier theory given the electron moves around the nuleus but this was proven falsed after some time because as the molecule moves around the nucleus it will lose energy and ultimately lose full energy at all in revolving and the electron will be destroyed so what u have asked can be answered if u asked before the theory was proven false.( answer given is accurate i am a graduate student )

Answer 5

Electron spin is always present regardless of what is being done to the electron. This can only mean that there is an energy source that causes the electron to maintain a constant angular momentum. A spinning top or gyroscope has energy, but when either is disturbed, some of that energy is lost. Sufficient energy loss over a time will cause cessation of motion. In fact, with the possible exception of certain unseen subatomic "particles", we know of no thing without a known energy source which can maintain angular momentum when its energy is being removed.

Common sense and the law of conservation of energy would lead us to believe that electron spin is impossible, but electron spin is a well established fact that contributes to our quality of life today (with such things as magnetic resonance imaging). So the electron has spin whether we like it or not, and the fact that it exists forces us to conclude that the electron has a source of apparently inexhaustible energy which allows it to maintain its spin.

Every electron seems to have the same magnitude of spin and this magnitude does not appear to change. So the energy source that creates electron spin must have a governing mechanism to enforce a constant rate of spin at all times. This implies that the energy creating electron spin can be increased to offset the effects of any disturbance and decreased when the disturbance is no longer present. No material body in our world of larger natural objects has a means of maintaining angular momentum without an apparent energy source, and certainly no such object has an innate governed energy source to cause it to maintain precisely the same angular momentum at all times.

Answer 6

I can't really answer the question about what would happen if they don't spin around the nucleus. They do get energy from ambient conditions. Room temp, umm...25 degrees celsius maybe.... but thats 298 K. Where zero energy is at 0 K. Sort of..not quite, but its a good way to think of it.

Anyways, you are normally taught molecules have free rotation, because we deal with them at room temperature. If you dropped close to absolute zero, an ethane molecule would hit an energy barrier and not have free rotation.

But thats where electrons are getting their energy. From our surroundings.

I really don't konw if an electron would stop spinning at absolute zero, never thought of that before to be honest.

IF you take physical chemistry, you'll have a better understanding. How everything relates to entropy and thats based off of multiplicity. Can easily relate it to temperature.

Sorry if this is no help

Answer 7

...Experiments by J.J. Thomson in 1897 led to a look inside the atom and the discovery of a fundamental building block of matter
or in other worlds
the electron itself has turned out to be not quite the creature that J.J. Thomson thought it was. According to the quantum theory developed by Albert Einstein and others, it is a mistake to think that electrons must be either particles or waves but not both. Under some conditions electrons act like particles; under other conditions they act like waves. (The wave character of electrons was in fact experimentally indicated by J.J. Thomson's own son, G.P. Thomson, who as a result shared the Nobel Prize in 1937.) Physicists have also found that electrons are only the most common members of a whole "family" of related fundamental particles -- all of them infinitesimal points carrying charge, mass, and something called "spin." Why the particles have these properties remains a mystery, a grand challenge for the next century of research.

Answer 8

The ETC is the last part of aerobic respiration. This part of the ETC is when the oxygen molecule molecule that came from the atmosphere is used and creates the production of 32 ATP inside in the mitochondria. If oxygen isn't present, lactic acid fermentation will occur. If you also recall 2 NADH's were produced out in the cytoplasm as well during glycolysis. These will break apart into electrons / ions and find a way into the mitochondria to produce 36-38 ATP total.

Answer 9

the energy in spinning electrons come from the attraction by nucleus.if electrons do not revolve round the nucleas they will collide into nucleus due to attraction by nucleus

(it should be clear that Electrons do "revolve" around the nucleus in the general sense iff we consider its particle nature.if we consider wave nature then they do not "revolve"

Answer 10

Electrons :Atomic particle which posses energy(Negative) and in our daily life people are tuned to Current and this is due to flow of electrons from high potential gradient to lower gradient .If electrons dont revolve matter wont exists,this is due to the interaction between Electron and proton (positive +negative leads to destruction followed with Light )this positve ,negtive implosion is countered by Neutron .neutron acts asa interface between + n - charges ,the principle used in Atom bomb is removal of neutron so implosion takes place with big explosion
Electron movement is due to Centrifugal force attraction of nucleus,and in that force electron tend to spin and this spin is responsiable for the energy in electrons ,proximity increases the spin and thereby energy
