The wrong answer is The proton and electron both have a positive charge and the neutron has a neutral charge.
The electron, one of the components of the atom with neutrons and protons, is an elementary particle that has an elemental charge of negative sign (and not positive) located in the electronic cloud, its mass is 9.11 x 10 ^ (- 31) Kg.
The proton is a subatomic particle carrying a positive elemental charge.
