Hi:

I have a really basic question.
Evidently every basic particle as a corresponding anti-particle with the same mass but the opposite charge. How can a neutron have an anti-particle with the opposite charge?

Hello!
.
The anti-Neutron has the same mass of the Neutron, but, how the Neutron, don't has electrical charge. But has opposite baryon number - Neutron +1, anti-Neutron -1 - because the Neutron/anti-Neutron are composed by Quarks/anti-Quarks!

Some good references for reading: 1- Antineutron - Wikipedia, the free encyclopedia ; 2- Baryon number - Wikipedia, the free encyclopedia ; 3- Antiparticle - Wikipedia, the free encyclopedia .
