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?

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 !
