What did Rutherford's atomic model suggest about the structure of an atom?
What did Rutherford's atomic model suggest about the structure of an atom?
- The atom consists of a positively charged nucleus surrounded by negatively charged electrons. (correct)
- The atom's electrons are arranged in specific quantized energy levels around the nucleus.
- The atom is a solid, indivisible sphere with no internal structure.
- The atom contains a cloud of positive and negative charges distributed throughout its volume.
Which experiment led Rutherford to propose his atomic model?
Which experiment led Rutherford to propose his atomic model?
- Cathode ray tube experiment
- Photoelectric effect experiment
- Gold foil experiment (correct)
- Oil drop experiment
In Rutherford's gold foil experiment, most alpha particles passed through the foil because:
In Rutherford's gold foil experiment, most alpha particles passed through the foil because:
- The electrons in the gold atoms absorbed the alpha particles and re-emitted them in random directions.
- The alpha particles were repelled by the dense, positively charged nucleus of the gold atoms.
- The nucleus of the gold atoms was too small to deflect the alpha particles significantly. (correct)
- The alpha particles were able to penetrate the empty space within the gold atoms.
