Why do some of the alpha particles bounce back from the target?

Group of answer choices

These particles have head$-$on collisions with target nuclei.

The particles follow paths among atoms. Some of the paths turn around.

The particles that bounce back do so because they have the largest initial energies.

These particles haver nuclear interactions with some of the target nuclei.

The final direction of motion is determined by accumulation of collisions. The particles that bounce back do so because they accumulate a number of smaller backward deflections.

The particles that bounce back happen to encounter both electrons and nuclei in their paths.
