The correct answer should be a he told them that there can be other elements that would be in the world.
According to Thomson's atomic theory, the mass of an atom was special evenly throughout its volume. Errest Rutherford's experiment proved this wrong.
Probable you think to the Rutherford experiment.
positive
Rutherford's gold foil experiment demonstrated that atoms have a small, dense nucleus at their center, which contains most of the atom's mass, while the majority of the atom is empty space. This was evidenced by the deflection of alpha particles, indicating that a positive charge is concentrated in a tiny volume. The experiment led to the conclusion that the atomic structure is not a uniform sphere, as previously thought, but rather a nucleus surrounded by orbiting electrons. This fundamentally changed the understanding of atomic structure.
The positively charged nucleus caused deflection. Positive charge is because of protons inside nucleus.
A scientist who made an expirament that was better then rutherfords expirament his was more avanced becuase with milikan's expirament you could study one drop at a time but rutherfords expirament requird you to study the whole cloud and by stuying the drop you could figure more out about the substance.
Because Joel is the man
Ernest Rutherford's famous "gold foil" experiment changed the way we though of atomic structure. His demonstration proved that atoms have a small, dense nucleus which contains protons and neutrons. The electrons were shown to be outside the nucleus. Prior to this, we thought atoms had a consistent structure throughout, like soup or pudding.
Jane Goodall, known for her research on chimpanzees, is a scientist not associated with the study of atomic structure. She is a primatologist and anthropologist who has made significant contributions to the field of animal behavior and conservation.

The scientist who first postulated the theory of atomic structure was John Dalton. He proposed his atomic theory in the early 19th century, suggesting that elements are composed of indivisible particles called atoms.
Ernest Rutherford is the scientist who conducted the gold foil experiment in 1911 and discovered that atoms have a small, dense nucleus at their center. This experiment led to the isolation and identification of the atomic nucleus.
