How may sub-atomic particles are present in an a-particles used in Rutherford's scattering experiment?
- A. No. of Protons - 4 No. of Neutrons - 0, No. of Electrons - 0
- B. No. of Protons - 2. No. of Neutrons - 0, No. of Electrons - 2
- C. No. of Protons - 2 , No. of Neutrons - 2, No. of Electrons - 0
- D. No. of Protons - 2 No. of Neutrons - 2, No. of Electrons -
Step-by-step solution
An alpha (α) particle is a helium nucleus, consisting of 2 protons and 2 neutrons, and has no electrons. Therefore, it has 2 protons, 2 neutrons, and 0 electrons.
