Which of the following is/are deduced from the Rutherford’s scat...
The correct answer is option (B): (2) only.
Explanation:
Rutherford's scattering experiment was performed by Ernest Rutherford in 1911. In this experiment, a beam of alpha particles was directed at a thin gold foil. Based on the observations from this experiment, we can deduce the following:
1. There are neutrons inside the nucleus:
Rutherford's experiment did not provide any direct evidence for the existence of neutrons. Neutrons were discovered by James Chadwick in 1932, several years after Rutherford's experiment. Therefore, the presence of neutrons inside the nucleus was not deduced from this experiment.
2. The sign of the charge of the nuclei is the same as the sign of alpha particles:
Rutherford's experiment revealed that most of the alpha particles passed through the gold foil undeflected, but a small fraction of them were deflected at large angles. This observation led Rutherford to propose that the positive charge of an atom is concentrated in a tiny, dense nucleus at the center. Since the alpha particles are positively charged, their deflection implies that the nucleus itself must be positively charged. Therefore, Rutherford's experiment deduced that the sign of the charge of the nuclei is the same as the sign of the alpha particles.
3. Electrons are embedded in the nucleus:
Rutherford's experiment did not provide any evidence for electrons being embedded in the nucleus. In fact, Rutherford's model of the atom proposed that electrons orbit around the nucleus in a manner similar to the planets orbiting the sun. This model, known as the planetary model, suggests that electrons are located outside the nucleus and not embedded within it.
In conclusion, based on Rutherford's scattering experiment, we can deduce that the sign of the charge of the nuclei is the same as the sign of the alpha particles. Therefore, the correct answer is option (B): (2) only.
