Which of the following is an incorrect statement about the Rutherford scattering experiment?
A)Most of the alpha particles directed at a very thin gold foil passed right through the foil, undeflected from their straight-line path
B)As a result of the experiment, the atom is pictured as consisting mostly of open space
C)The few alpha particles that were on a collision course with the gold electrons were repelled backward at acute angles
D)The experiment led to the conclusion that the nucleus of an atom contains all of the atom's positive charge
E)The experiment provided a partial understanding of the location and charge of the particles within the atom

Quizplus · Accepted Answer

The incorrect statement is that the few alpha particles that were deflected at acute angles were repelled by the gold electrons. In reality, these alpha particles were deflected by the nucleus of the gold atoms, not the electrons. The nucleus contains protons, which have a positive charge that repelled the positively charged alpha particles.
