In a perfectly isolated atom electrons turns around the proton continiously. Their energy comes from where?

Answer 1

running into each other

Answer 2

Energy is not needed to keep it moving. Once it is in 'orbit', it stays there. This is just like what happens with planets orbiting the sun, by the way. There is a slight twist with electrons since accelerating chargews usually emit energy and going around in a circle will be an acceleration. This was a big problem at one point because it was predicted that atoms would decay in a small fraction of a second from this effect. However, in quantum mechanics the electrons don't emit radiation and the atoms are stable.

Answer 3

The electron is formed of electromagnetic energy. The state (condition) of the electromagetic energy may change when it is formed into an electron, but the value of "c" that formes the electron does not change. Because the value of "c" remains, what is formed about an atom are shells of frequecy that exist as waves, having the value of "c".

When an electron is formed, it has a magnetic, electric, and mass value, yet these are wave in nature as is the energy that forms it.

Answer 4

Electrons only expend energy, in the classical sense, when they are accelerated. The configuration that the electron takes up in an atom is called a stationary wave: a wave that is fixed according to time and space--relative to the atom that it is attached. Therefore, since the wave is stationary it is not accelerating and releases no energy. In quantum physics you might say that an electron expends energy only when its wave function accelerates.

Answer 5

Their energy comes from their mass and velocity. In a perfectly isolated atom there is nothing to impose friction on the electron, and its velocity remains constant. (Newtonian--Einsteinian will make for small corrections, depending on the mass-energy of the electron)

Answer 6

wow so many views..i think its on the charges of these particles...since the proton is +ve and electrons negetive they attract eachother but then the electrons themselves repel eachother....these force of attraction ane repulsion make them move ina circle.

Answer 7

Though we name various particles (many entirely hypothetical) and assign properties to them, (gluons, photons, gravitons, tachyons) it's still hard to get away from the notion of a Creator and Sustainer isn't it? Science is great at cataloging and associating things, and even predicting future events to a degree. But it never seems to be able to answer where anything ultimately comes from. There's always, "Well, where did that come from?"

Answer 8

Like Magnets, their energy is part of thier makup, part of the dynamic which ties the protons and neutrons together.

Answer 9

Good question.
Perhaps a spinning nucleus activates the electrons.
So what makes the nucleus spin? ...the moving electrons?
