How do electrons and other particles get the energy to orbit the nucleus?

Answer 1

The increased energy that atoms receive is from an external source of radiation . On earth the energy received is from the sun.The electrons increases in mass when it receives extra energy . In order to maintain rotational equilibrium as it increases in mass,it must expand it its orbital radius.The result is a longer period and a slower motional velocity.
Here we have a case of mass increase with velocity decrease.

Answer 2

To maintain an orbit around the nucleus, the electrons travel at a speed that produces a counterforce equal to the attraction force of the nucleus. Just as energy is required to move a space vehicle away from the earth, energy is also required to move an electron away from the nucleus

Answer 3

The question doesn't really make sense. A proton and an electron have more energy independently than they do as a hydrogen atom. So the question should be:

Where did the extra energy go when the atom was formed?

And the answer is: when an electron drops into orbit around a nucleus, it releases energy in the form of one or more photons.

Answer 4

Electrons exist in "orbit" as a kind of standing wave (probability wave) and the energy levels needed to exist in those waves are the allowed energy values for each electron. As an electron falls to a lower energy orbital it emits a photon that has the same amount of energy as the difference between the orbitals. A photon with exactly the right amount of energy can raise an electron to a higher orbital. No energy is required to maintain a stable electron in an orbit.

Answer 5

generally electrons do not get energy.but they revolve due to the balance between centripetal & centrifugal forces....
