Electron vs Quark Size Name: Tania N. If a proton/neutron is
very much larger than an electron, is a quark bigger or smaller
than an electron? -- Question from one of my little year
seveners. (grade~2) A quark has never demonstrated any
measurable size. Like an electron, it is a "fundamental
particle", one of the few particles from which all else is made.
The size of a proton or neutron comes from the motion of the
quarks as they orbit around each other, sending energy and
particles(called mesons) back and forth between each other. The
three quarks are the primary particles of a proton/neutron, the
particles that identify the proton or neutron for what it is.
Still, the proton/neutron is essentially a cloud of motion with
low energy particles flashing in and out of existence all the
time. It is this cloud of motion that gives the proton/neutron
its size. Dr. Ken Mellendorf Illinois Central College It takes
"seveners" to ask those questions we wish we had asked in
