antielectron
Positive charged lepton
Antielectron is a technical term for positron—the antimatter counterpart of an electron.
It has the same mass as an electron but carries a positive charge instead of negative.
When an electron and antielectron meet, they annihilate each other, converting their mass to energy.
Positron is more common in scientific usage.
