Question:

Hans Geiger and Ernest Marsden experiment?

I'm a little confused with some homework i've been given.The question is quot;Hans Geiger and Ernest Marsden disproved the plum pudding model by firing alpha particles at a sheet of aluminium foil and measuring the deflection of the particles.True or Falsequot;In my text book it says they used gold foilSo is gold foil the same as aluminium foil is what i'm really asking I guess?

Answer:

it was gold foil but aluminum could have worked as well since the experiment showed that atoms are mostly empty spacei would say false due to the fact that it was gold and not aluminum
