Question

in 1909, ernest rutherford carried out the gold foil experiment. in this experiment, positive alpha particles were used to bombard gold foil. most passed through the gold foil undeflected. what conclusion was made about the structure of the atom based on this observation? en 1909, ernest rutherford llevó a cabo el experimento de la lámina de oro. en este experimento, se utilizaron partículas alfa positivas para bombardear la lámina de oro. la mayoría atravesó la lámina de oro sin desviarse. ¿qué conclusión se llegó a la estructura del átomo con base en esta observación?(6a) a alpha particles do not exist b an atom is mostly empty space c atoms do not have a nucleus. d positive charges are attracted to positive charges

Explanation:

In Rutherford's Gold Foil Experiment, most alpha particles passed through the gold foil undeflected. This suggests that the atom has a large amount of empty space. If the atom were solid (with no empty space), the alpha particles would have been deflected more significantly. Options a (alpha particles do not exist) is incorrect as alpha particles are real. Option c (atoms do not have a nucleus) is wrong because the experiment actually led to the discovery of the nucleus (though this option is refuted by the fact that some particles were deflected, indicating a dense, positively - charged nucleus which is not relevant to the undeflected majority). Option d (positive charges attract positive charges) is against the principle of like - charge repulsion.

Answer:

b. An atom is mostly empty space
