Question

in 1909, ernest rutherford performed an experiment to explore the atomic structure. in his experiment, he projected high - speed positively charged α particles onto a thin gold foil. he found that all α particles did not follow the same path. many particles passed through the foil without any scattering, implying that most of the space in an atom is empty. some particles were scattered at a large angle, and very few of them scattered back in the direction from which they had come. based on these observations, rutherford proposed an atomic model, which is known as rutherfords atomic model.
part a - conclusions from rutherfords experiment
watch the animation depicting rutherfords experiment and choose which of the following conclusions are correct.
check all that apply.
view available hint(s)
the atom does not have positively charged parts.
the atom contains a positively charged nucleus.
a positive charge is condensed in one location within the atom.
the majority of the space inside the atom is empty space.
a positive charge is spread equally over the atom.
the atom is a very compact entity without any empty space.

Explanation:

• Rutherford's experiment showed that most of the atom is empty space (as many α - particles passed through the foil without scattering).
• Some α - particles were scattered at large angles, which implies that there is a positively charged, dense nucleus (a positive charge condensed in one location).

Answer:

• The atom contains a positively charged nucleus.
• A positive charge is condensed in one location within the atom.
• The majority of the space inside the atom is empty space.
