Question

which experiment lead to the discovery of the atomic nucleus?
thomson - cathode tubes
dalton - observation
rutherford - gold foil
mendeleev - periodic table

Explanation:

Rutherford's Gold Foil experiment showed that most of the atom is empty space with a small, dense, positively - charged nucleus at the center. Thomson discovered the electron using cathode tubes. Dalton's work was on atomic theory in general, not specifically the nucleus. Mendeleev created the periodic table.

Answer:

C. Rutherford - Gold Foil
