Question

In an alpha scattering experiment, few alpha particles rebounded because

Most of the space in the atom is occupied

Positive charge of the atoms very little space

The mass of the atom is concentrated in the centre

All the positive charge and mass of the atom is concentrated in small volume

​

Answer 1

Answer:

In an alpha scattering,few alpha particles rebounded because both alpha particle and nucleus have positive . So,the both of these particles repel each other and nucleus is very dense so alpha particles rebounded.

Answer 2

In an alpha scattering experiment, few alpha particles rebounded because

3. The mass of the atom is concentrated in the centre

• In the alpha scattering experiment, we use a gold foil treated with certain chemicals and is targeted at with a beam/laser for observation purposes.
• Most of these beams passed through the aurum plates with little to no difficulty.
• But certain beams rebound as they've interacted with something making them retrace.
• Thus, Rutherford's experimental hypothesis was proved right and the fact was established that the mass of the atom is concentrated in the centre.
