An antiparticle is a subatomic particle corresponding to another particle with the same mass, spin and mean lifetime, but with charge, parity, strangeness and other quantum numbers flipped in sign.
When a particle of matter meets its corresponding antiparticle of antimatter, they annihilate each other, converting their mass into energy. This process releases photons and other elementary particles, following Einstein's famous equation E=mc^2.
No. Antimatter and dark matter are two entirely different things. Dark matter is a form of matter (for lack of a better word) that only interacts with ordinary matter via gravity. Antimatter is matter consisting of antiparticles. For every normal particle type there is an antiparticle of the same mass but opposite charge. If a particle meets its antiparticle the two annihilate each other and turn into energy.
The antiparticle of a positron is an electron. Both the positron and electron have the same mass but opposite charge, with the positron having a positive charge and the electron having a negative charge.
When a particle and its antiparticle meet, they are converted into energy. The amount of energy is described by the famous equation e = mc2
The first antiparticle discovered was the positron, which is the antiparticle counterpart to the electron. It was predicted by Paul Dirac in 1928 and confirmed experimentally by Carl Anderson in 1932.
The anti-matter equivalent of an electron is a positron. Positrons have the same mass as electrons but have a positive charge. When a positron and an electron collide, they annihilate each other, releasing energy in the form of gamma rays.
Answer 1There are three different types of neutrinos. Each one is associated with its own antiparticle, but is not an antiparticle itself. Answer 2Particle and antiparticle are distinguished by their charges. The positron, for example, the antiparticle of the negatively charged electron, is positively charged. The neutrino, on the other hand, is electrically neutral-the prerequisite for the ability of being its own antiparticle. However, I assume that the antiparticles of neutrinos are neutrinos with opposite spinning direction.
