why cant a electron loose energy and fall into nucleus?

Question

everyone fails to answere.the answere is in that case it will need velocity more than speed of light which is imposible to reach

Answer 1

it doesnt lose energy because it travels in its own energy level.

if it is excited 2 a higher energy level, it will return 2 its original energy level and liberate energy.

u hav 2 provide energy 2 excite it.

it wont fall into the nucleus because it doesnt lose any energy while travelling in its energy level.

Answer 2

Try this on for size people:

Electrons are not particles. They are quantum entities that can only be accurately described by mathematics. No one can truly comprehend what is an electron, not even Nobel-prize winning physicists. The human brain is conditioned by experiences in a limiting 4-dimensional world (3 of space, one of time) that it is impossible to comprehend what is an electron. Nevertheless, it can be described mathematically. Unfortunately, the mathematical equation that describes an electron interacting with anything other than a single proton is too complex and unwieldy for even the most powerful computers to date. The only system that we can model with absolute precision is the hydrogen atom (one electron and one proton) in an ideal vacuum. Solve Schrodinger's equation for the hydrogen atom, and you get the probability density of "finding" the electron at various points in space around the nucleus. If you plug in the location for the surface of the proton (i.e. the surface of the nucleus) for the hydrogen atom in the ground state, you will calculate that there is a 13% probability of finding the electron there. In other words, the electron spends 13% of its time on the surface of the nucleus! How can this be? That doesn't make sense? That's impossible? Remember, in quantum mechanics, there is no place for "common sense." Common sense is nothing more than a filter by which we see the world. And we see the world on a scale that, for the most part, hides quantum effects. In other words, when you are talking about quantum physics, if something doesn't make sense, that means that you are prejudiced in your view of what is going on. You must stop thinking that subatomic particles should behave like baseballs. They don't, and there is nothing wrong with that. What is wrong is to try to use your "experiences" to understand and explain quantum behavior. The electron "exists" at all points in space around the nucleus, and the probability density distribution has a maximum that corresponds to the ground-state distance from the nucleus. This is the "stable orbit" distance to which people refer. However, the probability of finding the electron at other locations in the ground state is still significant, and includes 13% of the time at the nuleus' surface. Weird, but that is what is exciting about quantum theory.

So everyday experience should not be applied to quantum behavior. Does this mean that one can learn what is quantum behavior? Unfortunately no, because no matter what, we are constrained to live in, and therefore view our universe, in a 4-D world, and a macroscopic one at that. The quantum view is not constrained to just these dimensions. And so sadly, we can never truly understand the quantum universe (although we can do our best to describe things mathematically). If you want to learn more, read anything by Paul Davies or John Gribbin.

Answer 3

classical mechanics predicts that an electron will lose energy as it revolves around the nucleus. and hence the radius of the rotaiong electron will reduce with time till a point when the electron will collapse into the nucleus.

however the electron does not lose energy as it travels round the nucleus. this is explained by bohr in quantum mechanics. bohr predicted a study angular momentum. and that the circumference of the in a mutiple of the wavelengh. it is related by the equation

2Лr=n λ

where n the nprincipal quantun number cannot be equal to zero.
hence the electron cant fall into the nucleus.
the distance is not allowed to be zero.

Answer 4

When it loses energy it does fall to a lower energy level . But even at the lowest energy level it is still spinning in an opposite direction as its pair across from it and traveling at very great speed around the nucleus. It could go flying out as a tiny bit of energy.

Answer 5

According to Neils Bohr whenever an electron remains in its orbit it pocesses certain energy. However it can jump to a higher energy level by absorbing more energy or to a lower energy level by releasing energy. when ever the electron remains in an orbit its energy does not change. Also according to Einstein Energy can neither be created nor be destroyed. From all these we understand that electrons cant loose energy and hence they does not fall into nucleus

Answer 6

Since,the electron(which is a negatively charged particle) is under the action of the centrifugal force ,it revolves around the nucleus in circular orbitals and when there is a loss in its enargy ,it is transferred to the corresponding lower energy levels and hence it does not fall into the nucleus.

Answer 7

Electrons are charged matter and this sub atomic particle does not have mass. Loosing energy and falling into the nucleus can happen when there is a mass

Answer 8

u mite have studied Bohrs model...u will get ur answers by studying those postulates...That holds true for this...Rangdebas... answered almost rightly to ur question
And if u r nt beleiving this answer then tell me y it will need to attain velocity more than that of light..It will lose energy at every moment while revolving as it get accelerated (by electromagnetic theory) and its distance with nucleus will keep on decreasing and finally it surely will fall down in nucleus no matter wat the speed is...It will always lose energy if it revolves in a circular path bt when u define various energy levels for electrons then this will nt happen and will account 4 stability of atoms

Answer 9

according to classical law of thermodynamics any charged particle moving in a curved path should loose its energy continuously and fall into the nucleus but this does not happened as two different force acting which are known as centripetal and centrifugal forces and this was explained by Neils Bohr

Answer 10

hi ii is a stability that the electrons have with one yet another in the atom. as nicely by way of fact the nucleus.they are attracted yet stored at distance via the make up of the nucleus because it incredibly isn't any longer in basic terms one particle. yet made up of alternative factors. which entice and repel the electrons. hydrogen is the finest atom in spite of the incontrovertible fact that it incredibly is electron is stored in it incredibly is orbit.
