How fast does the electron orbit the Nucleus?

Question

Ok .......... any Physics Professors on???
These answers are pathetic!

Answer 1

That depends on the mass of the nucleus. What atom's nucleus ? The orbital speed should be less around a Hydrogen atom.Than an Einsteinium or Mendelevium Atom. The atoms Atomic mass or the Atomic number determine how fast the electron will orbit around the nucleus. The electrons orbital speed should be faster for a more massive atom. But, this not how it works at the scale of most atoms. Electrons,protons and neutrons are charged particles. Unlike planets. So,the same rules don't apply. Electrons don't neatly orbit the nucleus.Since Atoms are always in some kind of Chemical exchange where the trajectory of the electron is altered constantly.Due to Chemical reactions. (Except in minerals,ices,crystals and rocks.Where orbits are moe reasonable to accept). Also,Bigger atoms have more electrons. In different subshells or orbitals. So, for electrons in the Oxygen atom. There are 8 electrons orbiting Oxygen. The outer electron is different than the inner electrons speed. The inner electrons speeds are faster because,the orbital distance is shorter relative to the inner electrons distance form the nucleus.

Answer 2

There is no simple answer to that question.

One can do a back-of-the-envelope estimate of the
time scales involved by calculating the speed that an atom would attain.
These speeds would be appreciabe fractions of the speed of
light. Thus, the atom estimate would be inaccurate because
the atom model does not include relativistic effects.
When you add in the complication of allowing all of
the electrons in an atom to interact, well, not only
is there no closed-form solution, but even state-of-the-art
computational methods might not work (depending on the
nature of the relativistic corrections used).

this question is beyond K-12 science.

Best regards.

Answer 3

OK this is a tought one to answer in such a small space,
but there is no fixed speed, it depends on which orbit the electron is in, the farther away, the slower it goes.
you need to read up on quantum physics,
this link will give you an idea.

or if you want a basic answer, Very Fast! lol

Answer 4

depends on how hot the object is. at absolute zero it does not orbit at all, and increases it speed with increasing temperature.

Answer 5

quite correct, about 1/100th the speed of light

Answer 6

The more you know about one thing, the less you know about the other. Now I'm just rambling (but totally serious in this situation).

Answer 7

just under the speed of light

Answer 8

SO FAST IT WILL BREAK THE SOUND BARRIER 10X FOLD.... MINI SOUND BARRIER.
