In the Rutherford Bohr experiment one observation noted was that most alpha particles fired at the gold foil passed straight through. What does this tell us about the structure of the atom?

• The nucleus was positively charged

• The nucleus was negatively charged

• The atom was made up mostly of empty space

• The atom was very dense and tightly packed with nucleons

In the Rutherford Bohr experiment one observation noted was that some alpha particles fired at the gold foil were backscattered. What does this tell us about the structure of the atom?

• The nucleus was positively charged

• The nucleus was negatively charged

• The atom was made up mostly of empty space

• The atom was very dense and tightly packed with nucleons
