Question

which conclusion could be made from ernest rutherfords gold foil experiment?
atoms are made up of mostly empty space.
atoms are mainly solid and block alpha particles.
the volume of the nucleus is large compared to the rest of the atom.
the mass of the nucleus is small compared to the rest of the atom.

Explanation:

In Rutherford's gold foil experiment, most alpha particles passed through the gold foil undeflected, indicating that atoms are mostly empty space. The second option is wrong because most alpha particles passed through, so atoms aren't mainly solid. The third option is wrong as the nucleus has a very small volume compared to the atom. The fourth option is wrong because the nucleus contains most of the atom's mass.

Answer:

A. Atoms are made up of mostly empty space.
