Question 11 1 pts Which of the following experimental results suggested that the nuclear model on the right is a better presentation of the atomic structure over the raisin-pudding model on the left? Thomson proposed that small, negative electrons are embedded in a sphere of positive charge. Alpha Sphere of positive charge Atoms of the same element can have different masses, due to the difference in the numbers of neutrons in the nudeus. Millikan's oil experiment determined that the fundamental...
