Question

what is anti mattar? ​

Answer 1

Answer:

Antimatter is a material composed of so-called antiparticles. It is believed that every particle we know of has an antimatter companion that is virtually identical to itself, but with the opposite charge. For example, an electron has a negative charge.

Answer 2

Explanation:

In theory, a particle and its anti-particle (for example, a proton and an antiproton) have the same mass, but opposite electric charge and other differences in quantum numbers. ... Antimatter particles bind with each other to form antimatter, just as ordinary particles bind to form normal matter.
