Question

Rutherford’s α-particle scattering experiment led to the discovery of the ______.

Answer 1

Rutherford atomic model:

• Rutherford’s α-particle scattering experiment led to the discovery of the atomic nucleus.
• The positively charged particles and most of the mass of an atom were concentrated in a small volume.
• He called this region of the atom a nucleus.
• The Rutherford model proposed that the negatively charged electrons surround the nucleus of an atom. He also said that the electrons surrounding the nucleus revolve around it at a very high speed in circular paths.
• He named these circular paths orbits.
• Electrons being negatively charged and nucleus being a densely concentrated mass of positively charged particles are held together by a strong electrostatic force of attraction.

Therefore, Rutherford’s α-particle scattering experiment led to the discovery of the atomic nucleus.
