Rutherford’s gold foil experiment showed several new things about the structure of the atom. Which results support the claim that the atom has a dense, positively charged core? Choose the TWO RESULTS THAT APPLY. (just tell me like 1 and 2 or 3 and 4) Some positive particles deflected at sharp angles.

Some negative particles deflected at sharp angles.

Most of the positive particles passed straight through the foil.

Some positive particles bounced back in the direction they came from.
