There is no evidence of a smaller particle than the quarks and electrons and other fundamental particles, but there is a theory of smaller particles called "rishons". The theory states that there are...
In physics, a quark (IPA: /kwɔrk/, IPA: /kwɑːk/ or IPA: /kwɑːrk/) is a type of subatomic particle.[1] In technical terms, quarks are elementary fermions which strongly interact due to their...
Quarks are the elementary particles and in proton and neutron, there are 2 up quark and one down quark in proton and two down quarks and one up quarks in neutron. where as electron is a lepton and so...
The reason that protons are positive and neutrons have no charge is owed to the fact that quarks, which make up these particles, do not have integral charge. The charge of an up quark is +2/3, and...
