Which of the following is not true in Rutherford's nuclear model of atom:
(1) Protons and neutrons are present inside nucleus
(2) Volume of nucleus is very small as compared to volume of atom
(3) The number of protons and neutrons are always equal
(4) The number of electrons and protons are always equal
Ans: The number of protons and neutrons are always equal
