alpha2cen Posted December 20, 2010 Share Posted December 20, 2010 There is no one who don't know proton attracts electron. Why proton attract electron? You say "Do you say it as a question?" Compare proton and neutron, There is a little or big difference. Proton is made of two up quark and one down quark ,but neutron is made of two down quark and one up quark. This one difference make electron attraction phenomena. Why it is possible? Link to comment Share on other sites More sharing options...
timo Posted December 20, 2010 Share Posted December 20, 2010 The electron is attracted to the proton and not to the neutron because the proton has an electric charge while the neutron has not. In the quark image, just add up the individual electric charges of the quarks making up proton or neutron to see that. Not completely sure if that was your question, though.

swansont Posted December 20, 2010 Share Posted December 20, 2010 Protons and electrons attract because they have opposite charges. Why charges attract is the same kind of question as why masses attract. We don't know the answer to why, we observe that it does, and the science aspect of it is predicting/explaining what happens.

alpha2cen Posted December 21, 2010 Author Share Posted December 21, 2010 After inflation elementary particles were created. Energy-------------->matter(proton, neutron, electron, neutrino) +anti-matter Which one is the first created? proton <------------------->proton (repulsion) proton >-------------------<electron(attraction) If this property were not existence, very big proton(cause of the gravity) and very big proton electron mixture (cause of the gravity) would be created. The problem is which property of the proton attract electrons. Link to comment Share on other sites More sharing options...
swansont Posted December 21, 2010 Share Posted December 21, 2010 The property is the charge. They interact electromagnetically, primarily. Link to comment Share on other sites More sharing options...
alpha2cen Posted December 30, 2010 Author Share Posted December 30, 2010 (edited) Is the property changed at any conditions? For example very high temperature or 0K. At hight gravity the attraction property is useless. Edited December 30, 2010 by alpha2cen Link to comment Share on other sites More sharing options...

alpha2cen Posted December 31, 2010 Author Share Posted December 31, 2010 (edited) The funny thing is that electron- proton don't stick together. Between electron and proton have some distance. They are very attractive, but have some distance. What's the problem? Edited December 31, 2010 by alpha2cen Link to comment Share on other sites More sharing options...

lemur Posted December 31, 2010 Share Posted December 31, 2010 Quantum mechanics, specifically the Heisenberg Uncertainty Principle. The electron cannot be confined to such a small space. Does the electron's position become more sporadic as it accelerates closer to C? Are atomic electrons constantly accelerating/falling into the nucleus and then reconstituting themselves elsewhere as they "dissolve" into wave-energy?

swansont Posted December 31, 2010 Share Posted December 31, 2010 Does the electron's position become more sporadic as it accelerates closer to C? As its speed increases its wavelength decreases, so you could say its position becomes better defined. Are atomic electrons constantly accelerating/falling into the nucleus and then reconstituting themselves elsewhere as they "dissolve" into wave-energy? This makes no sense. It doesn't represent physics as I know it. Link to comment Share on other sites More sharing options...
IM Egdall Posted December 31, 2010 Share Posted December 31, 2010 In Feynam's QED approach, inside an atom photons are constantly being sent back and forth between electrons and protons. This photon messenger particle is what keeps the probability of finding an electron highest outside the nucleus. (Feynman's classic QED,The Strange Theory of Light and Matter explains this.)

It doesn't represent physics as I know it. It just occurred to me that maybe electrons could accelerate through the electrostatic field of the nucleus and that their increasing energy could cause them to "jump around" more as an effect of energy-additions at relativistic speeds. I don't understand what governs the trajectory of their motion, if they even have a trajectory. When you say their frequency increases, does that mean they travel in a "beam" similar to light?

This photon messenger particle is what keeps the probability of finding an electron highest outside the nucleus. (Feynman's classic QED,The Strange Theory of Light and Matter explains this.) Why, because the photon emitted outward from the nucleus bumps electrons outward? Link to comment Share on other sites More sharing options...

But, At 0K Bose-Einstein condensation is occurring. They can be same place. Next, when we heat up, electron and proton are separated again?

Next, when we heat up, electron and proton are separated again? BECs happen at T>0. They are close, but not at 0K. BECs do not involve electrons residing in the nucleus.

alpha2cen Posted January 3, 2011 Author Share Posted January 3, 2011 At the high temperature electrons are moving more freely without restricted to very small place. We call that state plasma. How can we calculate the temperature at which the gas is existed as plasma? Which distance is the limit between plasma and gas molecules? Link to comment Share on other sites More sharing options...

steevey Posted January 16, 2011 Share Posted January 16, 2011 The top modern theory on why charges occur is of a new particle called the "Gauge Boson" which is suppose to be the force carrier for particles. There are different types of Gauge Bosons which are given off by particles, and in a nut-shell analogy, they "snap back" to the parent particle they were emitted from like a rubber band, at least for the Gauge Bosons with mass. The Gauge Bosons with mass have a finite duration throughout space, and the more mass a Gauge Boson has, the shorter it's existence is. However, the Gauge Boson for gravity and the electromagnetic force has no mass which is why their force get's carried through space indefinitely, but getting much weaker as it travels through more space. I'm not sure how the Gauge Bosons "snap back" when they can travel indefanitely through space, but Gauge Bosons can be exchanged by other particles.
