Question

In an alpha scattering experiment,few alpha particles rebounded because

Answer 1

Explanation:

In an alpha scattering experiment alpha particles are allowed to pass through a thin gold foil. The scattering takes place as follows :

• Most of the particles move without any deflection. This is because most of the space inside the atom is empty.
• Some of the particles get deflected through small angles, this shows the presence of a positive charge concentration in the centre of each atom i.e the nucleus.
• Some atoms get deflected through large angles or retrace their path. This is because these particles are directed at the centre of the nucleus and thus experience severe repulsion.
