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
Explanation:
The sum of protons and neutrons give the mass number, the number of neutrons can be very different to the number of protons.

Rutherford's alpha-particle scattering experiment was responsible for the discovery of
1 Electron
2 Proton
3 Nucleus
4 Helium
Explanation:
Rutherford's alpha-particle scattering was responsible for the discovery of atomic nucleus. Nucleus contains most of the mass. Most of atom has empty space.
