Question

State rutherfords observation is based on his alpha scattering experiment. What conclusions did he draw from the observations?

Answer 1

• The "Rutherford nuclear atom" and the "Rutherford Planetary Model" were other names for the Rutherford atomic model.
• Rutherford described the nucleus of the atom as a tiny, compact, and positively charged core in 1911.
• Rutherford discovered that an atom's mass is concentrated inside its nucleus.
  Rutherford's observations:

Rutherford made the following observations during his scattering experiment;

• The majority of the alpha particles flowed right through the gold foil.
• Some were redirected at modest angles, while others were redirected at enormous angles.
• Only a few seemed to recover.

Conclusions are drawn by Rutherford from the observations from his experiment :

• Most of the space in one atom is unoccupied since a huge number of the Alpha-particles discharged at the gold sheet passed through it without deflection.
• The alpha particles were deflected at minor angles by the gold sheet, causing the negative charge for each atom to be distributed equally.
• Only very few alpha or helium particles are deflected back, implying that only a few alpha particles have deflection angles of around 180 degrees. As a result, positive protons inside an atom make up a tiny fraction of the atom's entire volume.
