Question 1a) The diagram below shows a plan view of the apparatus used by Rutherford and his team which led them toproposing the nuclear model of the atom.Alpha source in leadcollimatorGTravelling microscopewith phosphorescentscreenGold foilDescribe how the apparatus was used to probe the microscopic structure of matter. [Suggested word count 150]b) Whilst the vast majority of alpha particles passed through the gold foil with little or no deviation, a smallfraction of them were scattered through larger angles, some even backwards. Commenting on these findingsRutherford wrote "It was almost as incredible as if you fired a 15-inch shell at a piece of tissue paper and it cameback and hit you."

When a bound electron moves to location further from the nucleus, which of the following are true? energy of electron increases because it takes energy input to separate positive and negative charges, and there is a decrease in the electrostatic potential energy of the electron energy of electron increases because it takes energy input to separate positive and negative charges, and there is an increase in the electrostatic potential energy of the electron energy of electron decreases because energy is released as positive and negative charges are separated, and there is a decrease in electrostatic potential energy of electron since it is now further away
