Question

What experimental evidence led to the development of this atomic model from the one before it?

Answer 1

A few of the positive particles aimed at a gold foil seemed to bounce back. Scientists have changed the model of the atom as they have gathered new evidence. One of the atomic models is shown below.

Answer 2

"Hope the below explanation will help you:

Rutherford's experimental evidence led to the development of this atomic model from the one before it.

According to him, a few of the positive particles pointed at a gold foil appeared to ricochet back off of the light metallic foil.

This experimental evidence gives the root the development of the atomic model.
