Question

how anti matter is made

Answer 1

Positrons are commonly produced by radioactivity – they're a byproduct of β+ decay, in which a proton in the atomic nucleus transmutes into a neutron. Other antiparticles result from high-energy collisions, in which the excess energy produces pairs of particles and their antimattercounterparts.

Answer 2

Explanation:

Antimatter is a material composed of the antiparticle partners to the corresponding particles of ordinary matter.

For example , in Matter , a proton has positive charge while in an Antimatter, an antiproton has negative charge.
