A) since gold has more no. of protons it will deviate alpha particle most.that's my answer not sure.if correct please tell me

Answer:



The deviation of alpha particles is a phenomenon that occurs when alpha particles pass through a thin foil. The extent of deviation depends on the properties of the foil and the velocity of the alpha particles.



The extent of deviation of alpha particles passing through a foil depends on the properties of the foil. The foil's thickness, density, and atomic number determine how much the alpha particles will deviate from their path. The velocity of the alpha particles also determines the extent of deviation.



The highest deviation of alpha particles will be for gold, copper, and aluminum foils.



Gold foil has a high atomic number, which means that it has a high density of protons in its nucleus. The alpha particles passing through gold foil will experience a strong Coulombic interaction with the gold nuclei, resulting in a high degree of deviation.



Copper foil also has a high atomic number and a high density of protons in its nucleus. The alpha particles passing through copper foil will experience a strong Coulombic interaction with the copper nuclei, resulting in a high degree of deviation.



Aluminum foil has a lower atomic number than gold and copper, but it still has a high density of protons in its nucleus. The alpha particles passing through aluminum foil will experience a weaker Coulombic interaction than they would in gold or copper, but the extent of deviation will still be significant.



In conclusion, the highest deviation of alpha particles will be for gold, copper, and aluminum foils. The extent of deviation depends on the properties of the foil and the velocity of the alpha particles.
