Which of the following is NOT true regarding Rutherford's Gold Foil experiment?

- It effectively disproved the Plum Pudding Model because most of the radiation went through.

- It confirms the existence of a dense nucleus and a mostly empty atom.

- The area around the nucleus must be of low mass.

- The scattering of the beta particles confirmed that the nucleus was positively charged.

The area around the nucleus must be of low mass.

Explanation:

Rutherford's experiment showed that there are some positive charges in the center of the atoms, and because they are all together, they will give a great mass to the atom.

It was quite different from Thomson's experiment, in which it was thought that the negative charges were mixed with the positive charges, around the atom (like a Pudding Model). In Rutherford's experiment, because the direction of beta particles, it was the prediction of the positive nucleus.
