Rutherford's famous experiment with $\alpha$-particles used this metal
1 $\mathrm{Ni}$
2 $\mathrm{Au}$
3 $\mathrm{Fe}$
4 $\mathrm{Zn}$
Explanation:
Rutherford conducted an experiment by bombarding a thin sheet of gold (Au) with $\alpha$-particles and then studied the trajectory of these particles after their interaction with gold foil.

Which of the following is incorrect regarding Rutherford's atomic model?
1 Atom contains nucleus
2 Size of nucleus is very small in comparison to that of atom
3 Nucleus contains about $90 \%$ mass of the atom
4 Electrons revolve around the nucleus with uniform speed.
Explanation:
According to Rutherford's majority of the mass was concentrated in a minute positively changed region (the nucleus surrounded by electrons).
