# 1. Explain Rutherford’s gold foil
experiment and the conclusions he reached.
Helium nuclei were bombarded at a piece of gold foil. Amazingly some of the helium nuclei bounced back as if they had hit a brick wall when in fact they were being shot at a piece of toilet paper ( analogy) . Ritherford surmised the only way this could happen was if the centre of the atom was a dense concentration of positive charge ( protons) . Form this he deduced the nuclear atomic model.
# 2. A
4.0 cubic metre block of iron has a mass 31600 kg. Using proper problem solving format (i.e. showing ALL work ) find
the density of iron.
D=m/
D=
31600KG/4M3
D= ?????????
