question 14 1 pts what did rutherfords gold-foil experiments prove the existence of? the protons the entire atom the electrons outside the nucleus the nucleus

Explanation:

Rutherford's gold - foil experiment involved firing alpha particles at a thin gold foil. Most alpha particles passed through, but some were deflected at large angles. This showed that most of the atom's mass and positive charge were concentrated in a small central region, which is the nucleus. Protons' existence was not proven by this experiment alone, the entire atom was already known to exist in a general sense, and electrons outside the nucleus were proposed earlier (e.g., by Thomson). So the experiment proved the existence of the nucleus.

Answer:

the nucleus (the option corresponding to "the nucleus")
