" This common catalyst for fission reactions is composed of one up quark and two down quarks.
This particle was discovered in an experiment in which alpha particles caused the disintegration of beryllium. Crystal structures can be determined through a technique known as this particle's "scattering." This common catalyst for fission reactions is composed of one up quark and two down quarks. The number of these particles in an atom equals the difference of atomic mass and atomic number. For 10 points, name these subatomic particles found in the nucleus, which, unlike protons, have no charge.
