The correct order of increasing number of alpha particles passing unde

1.	The correct order of increasing number of alpha particles passing undeflected through the foils of Au. Ag, Cu and Al of 1000 atoms thickness each in a simulated alpha particle scattering experiment of Rutherford would be1. Au < Ag < Cu < Al 2. Al < Cu < Ag < Au3. Au < Cu < Al < Ag 4. Ag < Cu < Al < Au
Answer» Correct option: 1. Au < Ag < Cu < Al Explanation: Since decreasing order of the size of atom or nucleus : Au > Ag > Cu > Al ∴ The correct order of increasing number of alpha particles passing undeflected through the foils of Au. Ag, Cu and Al of 1000 atoms thickness each in a simulated alpha particle scattering experiment of Rutherford would be Au < Ag < Cu < Al Reason : As the size of nucleus increases, the deflection of alpha particles also increases for same thickness of foil.

Answer»

Correct option: 1. Au < Ag < Cu < Al

Explanation:

Since decreasing order of the size of atom or nucleus :

Au > Ag > Cu > Al

∴ The correct order of increasing number of alpha particles passing undeflected through the foils of Au. Ag, Cu and Al of 1000 atoms thickness each in a simulated alpha particle scattering experiment of Rutherford would be

Au < Ag < Cu < Al

Reason : As the size of nucleus increases, the deflection of alpha particles also increases for same thickness of foil.
