Discussion Overview

The discussion revolves around the behavior of protons and electrons in atomic structures, specifically addressing the forces that prevent electrons from being drawn into the nucleus and how they maintain their orbits. The scope includes conceptual explanations and comparisons to other physical systems.

Discussion Character

  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant questions what prevents electrons and protons from being stuck together and how electrons maintain their motion around protons and neutrons.
  • Another participant explains that the attractive force between protons and electrons acts as a centripetal force, similar to gravity keeping planets in orbit.
  • A participant inquires about an equation to calculate the strength of attraction between an electron and a proton, suggesting Coulomb's law as a potential reference.
  • There is a suggestion that the model of the atom being discussed may be outdated, with a recommendation to consider the concept of energy levels for electrons instead.
  • One participant uses an analogy involving a rope and a doorknob to illustrate the concept of energy levels and how they relate to electron orbits.

Areas of Agreement / Disagreement

Participants express differing views on the adequacy of the classical model of the atom, with some supporting the traditional view of centripetal force while others suggest a shift towards discussing energy levels, indicating a lack of consensus.

Contextual Notes

There are unresolved assumptions regarding the applicability of classical mechanics to atomic behavior, and the discussion touches on potentially outdated models without reaching a definitive conclusion on the current understanding of atomic structure.

Protons electrons...

What prevents electrons and protons from being stuck togeather? how do they just keep flying around the protons and nutrons?

The attractive force is what keeps the electrons flying around the nucleus instead of just flying off. This behavior is just the same as the way gravity keeps planets in orbit around a star or the way a slingshot keeps a rock in orbit around the holder's hand. The attractive force provides what is known as a centripetal force, which is responsible for continually changing the direction of the electron, thus keeping it in orbit.
 
ok and is there an equation for finding the strenght of attraction of an electron to a proton?

I would look for a definition of coulomb's law...I think this is what you want.

BTW is this not a rather outdated model of the atom? Shouldn't you be talking about the energy levels of the electron instead?
 
Hook up a rope to a doorknob, keep the other end in your hand. You can now make waves in the rope moving your hand up and down. To make a nice wave, you can go at different speeds, but not ANY speed. Each speed level is an energy level, depending on whether your wave has 1, 2, 3 ... bumps. Now imagine the distance between your hand and the doorknob is the circumference of the electron orbit. As long as the electron (the rope) has energy, it can't fall anywhere.
