Question

The nuclear model of the atom was presented in Chapter 2 of your textbook.  Which statement best describes this model?

It was consistent with scattering data in which alpha particles passing through a thin gold-foil were sometimes deflected at extreme angles.

In this model, the nucleus is a dense region of the atom where most of the mass and the postive charge are found.

Most of the atom is "empty space" with an electron moving in a region outside of the nucleus.

All of these statements (a), (b), and (c) are correct.
