Protons at maximum distance in nucleusNeutrons serve the purpose of seperating the repulsive proton- proton EM interaction. A neutron core keeps protons at a maximum distance from each other Offline #2 2007-11-25 20:09:03
Re: Protons at maximum distance in nucleusNo - doesn't the strong interaction bind together protons and neutrons - regardless of charge. The strong interaction is much stronger than the EM interaction. Mesons are exchanged betwen the nucleons which carry the strong interaction and effectively 'glue' the nucleons together - isn't this right? Offline #3 2007-12-03 06:34:58
Re: Protons at maximum distance in nucleusThe protons all repel each other to a maximum distance with a neutron core. Offline #4 2008-02-04 02:03:12
Re: Protons at maximum distance in nucleusMesons have a problem. Some are a combination of matter and antimatter; a quark and an anti quark. These mesons are matter antimatter combinations. This is nonsense. Offline #6 2008-05-06 08:37:43
Re: Protons at maximum distance in nucleusYou cannot say that electric proton repulsion has no consequence. Offline #7 2008-05-06 15:16:51
Re: Protons at maximum distance in nucleusYou are both right. Neutrons serve as "spacers" in the nucleus that provide binding energy (via the strong force) but no additional Coulomb repulsive energy. This is important because a nucleus composed only of protons is unstable. For this reason, heavier and heavier elements require a greater ratio of neutrons to protons to remain stable, because the higher atomic number increases the Coulomb repulsion energy.

Re: Protons at maximum distance in nucleusI believe neutrons are the core of the nucleus keeping the protons at maximum distance. Offline |
