Which activity best demonstrates ernest rutherford’s creativity?
with his well-known gold foil experiment in which he demonstrated that the atom has a tiny and heavy nucleus.
Answer is: B. designing an experiment to test the plum pudding model. Rutherford demonstrate that J.J Thompson’s Plum Pudding model was not accurate, but before testing, he thought that plum pudding model is correct. Rutherford theorized that atoms have their charge concentrated in a very small nucleus. This was famous Rutherford’s Gold Foil Experiment: he bombarded thin foil of gold with positive alpha particles (helium atom particles, consist of two protons and two neutrons). Rutherford observed the deflection of alpha particles on the photographic film and notice that most of alpha particles passed straight through foil. That is different from Plum Pudding model, because it shows that most of the atom is empty space.
B. designing an experiment to test the plum pudding model Explanation: Ernest Rutherford’s lies in designing the gold foil experiment which disproved the plum pudding atomic model.
From his gold foil experiment Rutherford concluded that most of the atom is made up of empty space, all positive charge lie in the center of the atom, and the center of the atom which contains all the mass of the atom in a small volume.
B. designing an experiment to test the plum pudding model. Explanation:
C. Explanation: Of the following activity best demonstrates the creativity of Rutherford: is making observations about the gold foil experiment. Rutherford’s Gold Foil Test confirmed the existence of a thin, enormous atom core that would later be recognized as an atom’s nucleus. To examine the effect of alpha particles on material, Ernest Rutherford, Hans Geiger and Ernest Marsden conducted their Gold Foil Experiment.
the correct answer is b
B. designing an experiment to test the plum pudding model
The answer is B, designing an experiment to test the plum-pudding model.
