Achilles Posted August 15, 2018 Posted August 15, 2018 And does it hold protons and neutrons together in the nucleus. Can you please tell me what it specifically does, thanks in advance.
Strange Posted August 15, 2018 Posted August 15, 2018 The strong force is what holds quarks together inside protons and neutrons. It is mediated by (virtual) gluons and is defined in terms of the "colour charge" of quarks and gluons. A proportion of the strong force "leaks" out of protons and neutrons and acts to old those particles together in the neutron.

Achilles Posted August 15, 2018 Author Posted August 15, 2018 Inside the proton or neutron are those quarks repelling each other or attracting each other.
swansont Posted August 15, 2018 Posted August 15, 2018 Just now, Achilles said: Inside the proton or neutron are those quarks repelling each other or attracting each other. They form a bound system, so what do you think the answer is? Could you bind these together with repulsive forces?
Achilles Posted August 15, 2018 Author Posted August 15, 2018 (edited) Well I was thinking that there was possibility they were repelling each other but the strong nuclear force keep them together... edit: and that the strong nuclear force is greater then the repulsive force between quarks if there was repulsion...

Strange Posted August 15, 2018 Posted August 15, 2018 There will be a repulsive force because they all have an electric charge, but this is much weaker than the strong force binding them together (hence the name!) 1
Sensei Posted August 15, 2018 Posted August 15, 2018 (edited) There is 3142 isotopes of 118 elements. Majority of them, significant majority, are unstable. Free neutron is also unstable and decays with mean-life ~15 minutes. Edited August 15, 2018 by Sensei
