Answer the following questions, which help you understand the difference between Thomson. Is the probability of backward scattering (i.e., scattering of ∝-particles at angles greater than 90° ) predicted by Thomson model much less, about the same, or much greater than that predicted by Rutherford ?
Answers
Answer ⇒ Yes. The Probability of the backward scattering (i.e., scattering of ∝-particles at angles greater than 90° ) predicted by Thomson model much less, about the same, or much greater than that predicted by Rutherford.
Explanation ⇒ We know that as per as the Rutherford Model of the atom, the nucleus is the heavy mass at the centre of the atom where as in the Thomson's model of the atom it is not so.
Thus, due to the heavy mass in case of the Rutherford model of the atom, the probability of the backward scattering, means the scattering of the alpha particles at an angle greater than that of the 90° is much higher than that of the Thomson model of the atom.
Hence, the given statement is correct.
Hope it helps.
Answer:
Yes. The Probability of the backward scattering (i.e., scattering of ∝-particles at angles greater than 90° ) predicted by Thomson model much less, about the same, or much greater than that predicted by Rutherford.
