Antiparticles are subatomic particles that have the same mass as one of the regular matter particles but the electric charge and magnetic moment are different. And the positron (positively charged electron) is the antiparticle of the electron that is negatively charged. Like the regular neutron, the spinning antineutron has a net electrical charge of zero but its magnetic polarity is opposed to that of a similarly spinning neutron. The neutrino, an unloaded particle that travels very close to the speed of light, spins in the counterclockwise direction as seen from behind, while the antineutrino spins in the clockwise direction as seen from behind. A particle and its antiparticle work together by annihilation to create electricity.
A particle and its anti-particle, in principle, have the same density but opposite electric charge and other variations in quantity. A proton, for example, has positive charge while an antiproton has negative charge.
Particles of antimatter bonds together to form antimatter much as ordinary particles bind to form normal matter. For example, a positron and an antiproton (the proton antiparticle) can form an antihydrogen atom. The antihelium nuclei were developed artificially with difficulties, and these are the most complex anti-nuclei found so far. Physical concepts suggest that complex atomic nuclei of antimatter, as well as antiatoms that correspond to the recognized chemical elements, are likely.
