According to QUANTUM PHYSICS, for every type of particle, there exists a corresponding type of ‘ANTI-PARTICLE’.
If one particle comes in contact with its anti-particle, both will ‘vanish’ releasing ENERGY! This process is called ‘ANNIHILATION‘.
An example of an anti-particle is a ‘POSITRON‘, also known as an ‘ANTI-ELECTRON‘, which is the anti-particle of ‘ELECTRON‘!
The charge on an anti-particle is opposite to that on its particle.
