rutherfords gold foil experiment showed that the atoms have ____ and j.j. thompsons experiment showed that the atoms have ________.

1. positive center (nucleus) and negatively charged particles (electrons), respectively
2. atomic orbitals and neutrons, respectively
3. cations and anions
4. none of the above

Explanation:

Rutherford's gold foil experiment demonstrated that atoms have a dense, positive - charged center (nucleus). J.J. Thompson's cathode - ray experiment showed that atoms contain negatively charged particles (electrons). Option 1 correctly matches the results of these two experiments. Option 2 is incorrect because Rutherford's experiment did not show atomic orbitals and Thompson's experiment did not show neutrons. Option 3 is incorrect as these experiments were not about cations and anions. Option 4 is incorrect since option 1 is correct.

Answer:

1. positive center (nucleus) and negatively charged particles (electrons), respectively
