Q. Why would Rutherford choose gold for his foil experiment?

A
It is an inert metal.
B
It has the highest electrical conductivity.
C
It is highly ductile.
D
It is highly malleable.
Solution:
  • Gold is the most malleable metal and he wanted the thinnest layer as possible.
  • Platinum is the most ductile metal. Gold, silver and platinum are inert metals.
  • Silver has the highest electrical conductivity.
  • Using this experiment Rutherford states that the atom is mostly empty space with a tiny, dense, positively-charged nucleus.
  • Based on these results, Rutherford proposed the nuclear model of the atom.
