Protons and neutrons are themselves made up of particles known as quarks and gluons. But matter can have an opposite in the form of antimatter. In fact, all the subatomic particles in matter either have their own anti-twins (antiquarks, antiprotons, antineutrons, and antileptons such as anti...
What is neutron emission? Why is energy released in the proton proton chain? Who discovered protons? What are vector-like quarks? What is light's elementary particle? What is quark-gluon plasma? What is a beta particle emitted from?
Fundamentally, matter is composed of elementary particles calledquarksandleptons, both of which are considered elementary particles in that they aren't made up of smaller units of matter. Quarks -- groups ofsubatomic particlesthat interact by means of astrong force-- combine into protons and neutr...
A particle composed of three quarks is classified as a: photon meson particon pion baryon Which quarks will you find in a neutron? only one answer is correct A: Three up quarks. B: Two up quarks and a down quark. C: Two down quarks and an up quark. D: One charm quark, one up ...
The theory that describes the strong nuclear force known as Quantum-Chromodynamics is notoriously difficult to solve. However, it can be simulated on supercomputers built and maintained at DOE facilities. DOE has been a leader in the study of quarks and gluons since the 1960s. The idea of quar...

Neutrons are uncharged particles found within all atomic nuclei (except for hydrogen). A neutron's mass is slightly larger than that of a proton. Like protons, neutrons are also made of quarks — one "up" quark (with a positive 2/3 charge) and two "down" quarks (each with a negative...
What happens when quarks are split? Splitting the Atom: When heavy atoms are split apart the energy that's released is greater than the energy required to split them which makes them a potential source of fission energy while light particles, like hydrogen release more energy when fused together...
The only “reason” is that if it were even a little different, life as we know it would be impossible. The masses of the proton and neutron almost coincide. Why? If the masses of either were even a little different, life as we know it would be impossible. The energy of empty space...
What is the smallest thing in the universe? Quarksare among the smallest particles in the universe, and they carry only fractional electric charges. Scientists have a good idea of how quarks make up hadrons, but the properties of individual quarks have been difficult to tease out because they...
