MCQ
Rutherford’s $\alpha$-particle experiment showed that the atoms have
  • A
    Proton
  • ✓
    Nucleus
  • C
    Neutron
  • D
    Electrons
✓

Answer

Correct option: B.
Nucleus
b
(b) In Rutherford's alpha particle experiment, the scattered alpha particle has large deflection angles. This experiment showed that the positive matter of atom was concentrated in an very small volume and it gave the idea of nucleus of an atom.
