Particles have a property that we call is charge because they show deviation in the ionized space.
What we call charged particles?
Charged particles are those particles which carry positive or negative charge on itself.
In the electric and magnetic field not all particles show activity, only those particles which carry charge will show activity in these field.

Hence, above explanation gives the evidence that supports the idea that particles have a property we call charge.
