equivalent of an electron

through a process called pair production
. Positrons are sometimes called "antielectrons".
The best anime ever, by far. It is about this sponge who works in a fast food place with his friend, Squidward.

When someone adds their own (or another person's) name to Urban Dictionary, either to flatter said person or to insult them. Urban Dictionamers don't realize that no one will read or care about these definitions. In the end, this is just extremely irritating and fills up the voting list (although I doubt the site's moderators will care enough to stop it).
60% of submitted terms are just people Urban Dictionaming themselves.
equivalent of a neutron
. Just like neutrons, antineutrons have no charge. However, antineutrons are made of antiquarks, which have the opposite charges of a neutron's quarks; as such, neutrons and antineutrons will annihilate upon contact.
Antineutrons have the same mass and charge as a neutron.
