Every subatomic particle has an antiparticle which if they meet and combine releases nothing but energy.  The antiparticle for an electron is a positron which has exactly the same mass as an electron but a positive charge.  There are also some particles like photons (The particle form of electromagnetic energy) which are their own antiparticles.

The collective term antimatter refers to antiparticles in general or a collection of antiparticles in one location.

This would only apply if we where located in an antimatter universe, an antimatter Earth in our present location would be a very unpleasant place to live!

Syhprum,

I know this, I was taliking bout an antimatter universe.

Our universe does contain  antimatter but in small quantities.

The "CERN" particle collider separated minute amounts of antimatter.
