During Rutherford's gold foil experiment, which two of the following happened?

• Some alpha particles passed straight through the foil

• All the alpha particles passed straight through the foil

• All the alpha particles were scattered through large angles

• Some alpha particles were scattered, some of them through large angles

In Rutherford's gold foil experiment:

The particles that went straight through...

• ... passed close to the positively charged nucleus

• ... passed through the empty space between the nucleus and the electrons

• ... hit the dense, positively charged nucleus

• ... passed through the nucleus
