Antihydrogen

Antihydrogen is an atom made of antimatter. Just as normal matter, antihydrogen can bond and form molecules with other antimatter – it would annihilate any normal matter that it touches. 

Structure

Antihydrogen has one positively charged positron orbiting a negatively charged antiproton. This is opposite to normal hydrogen, which has a negatively charged electron orbiting a positively charged proton.

As a molecule

Antihydrogen can also refer to the molecule called antihydrogen, which is made of two bonded antiprotons.
