Inquiry question: How is it known that atoms are made up of protons, neutrons and electrons?
Students:
● investigate, assess and model the experimental evidence supporting the existence and properties of the electron, including:
– early experiments examining the nature of cathode rays
– Thomson’s charge-to-mass experiment
– Millikan’s oil drop experiment (ACSPH026)
● investigate, assess and model the experimental evidence supporting the nuclear model of the atom, including:
– the Geiger-Marsden experiment
– Rutherford’s atomic model
– Chadwick’s discovery of the neutron (ACSPH026)
