12. QUESTIONS ON  SCATTERING Q1. What is the charge on an  particle ? Q2. Why should some  particles be repelled away from a nucleus? Q3. Why do most  particles pass straight through the gold atoms un-deflected? Q4. What has a plum pudding with currants and raisins got to do with early ideas of atoms?

13. Q1. What is the charge on an  particle ? POSITIVE + + Q2. Why should some  particles be repelled away from a nucleus? “LIKE CHARGES REPEL” Q3. Why do most  particles pass straight through the gold atoms undeflected? MOST OF AN ATOM IS EMPTY SPACE WITH A VERY SMALL DENSE NUCLEUS Q4. What has a plum pudding with currents and raisins got to do with early ideas of atoms? EARLY SCIENTISTS THOUGHT THAT PROTONS, ELECTRONS & NEUTRONS WERE EVENLY SPREAD OUT IN THE ATOM !
