Solution

The correct answer is C. α -particles are repelled by positively charged region.

In Rutherford's experiment, most of the α-particles passed straight through the gold foil, but a small fraction were deflected at small angles. This is because the α-particles, which are positively charged, are repelled by the positively charged nucleus of the gold atoms. This repulsion causes the α-particles to be deflected at small angles. The other options (A, B, and D) are incorrect because α-particles are not attracted by negatively charged particles, they are not pushed towards the heavy nuclear region, and they are not attracted by positively charged regions.

What did Rutherford and Marsden discover from the results of their scattering experiment?The positive charge is spread out across the atomThe negative charge is concentrated in the centre of the atomNeutrons have no chargeThe positive charge is concentrated in the centre of the atom

In Rutherford's famous experiment, he shot heavy, fast moving, positive alpha particles at a thin gold foil. Based on Thomson's plum pudding model of the atom, what did Rutherford expect to happen, and why? All the alpha particles would be deflected by the foil because of the even distribution of mass and charge throughout the atom. All the alpha particles would pass straight through the foil because of the even distribution of mass and charge throughout the atom. Most of the alpha particles would become embedded in the foil because they are attracted to the negative electrons in the atom. Some of the alpha particles would be deflected and some would pass through because of the negative charge of the electron cloud.
