Answer 2

Answer:

Neutrons are the particles in an atom which has neutral charge which means no charge.

It's evidence of existence come by the experiment that when electrons contains negative charge and protons contains positive charge then one particle also be for balancing these opposite charges otherwise both will not exist in an atom . Therefore this thought led to the assumption of neutrons
