Question

Quizplus · Accepted Answer

Particles and their antiparticles have opposite electric charges (A), opposite strangeness (B), and opposite charm (C). This is a fundamental property of particle physics known as charge conjugation. For example, the antiparticle of an electron (the positron) has a positive electric charge, opposite to the negative charge of the electron. Similarly, the antiparticle of a strange quark has opposite strangeness and the antiparticle of a charm quark has opposite charm.
