2.The net charge of an atom is neutral as there are equal amount af negative and positive charge imbaded in it or said in simple terms equal proton and equal electron each carrying equal amount of positive and negative charge each of quantity -/+ 1.602×10^-19 and they cancle each other.
3.Proton but not neutron as neutron is discovered by James Chadwick in 1932 and he founded positive
ely charged sphere in 1920.
hope you understand.
