This experiment helped to determine that most of an atom is actually empty space except for a very small positive core
What is Ernest Rutherford's gold foil experiment
300
This is the formula of aluminum oxide

It is any material that conducts electrons into or out of a media where electrochemical reactions are taking place
What are electrodes
