The correct answer should be a he told them that there can be other elements that would be in the world.
Yes , Rutherford's gold foil experiment was about the atomic structure. He bombarded 8000 alpha particles on the gold foil and the source of alpha particle was POLONIUM (an element in periodic table). After bombarding rays, he observed that most of the rays passed without deflecting, and few rays deflected backward. By this , he concluded that most part of the atom is empty. That empty part is also called extra nuclear part or energy levels, shells or orbit . Nucleus lies in the centre of the atom which carries positive charge. It was his assumption which was right. Because two like charges always repel each other. since alpha particles carries positive charge and it can repeled by only positive charge.
Electrons revolve in extra nuclear part.One thing that was wrong about Rutherford experiment was his assumption that eletron while revolving in the extra nuclear part continuously radiate energy.
That atoms have a positively charged nucleus.
According to Thomson's atomic theory, the mass of an atom was special evenly throughout its volume. Errest Rutherford's experiment proved this wrong.
very small relative to size of whole atomextremely densehighly positively charged
Probable you think to the Rutherford experiment.
was wandering the smae thing but i think they just developed rutherfords theory by doing the gold foil experiment in depth
positive
The positively charged nucleus caused deflection. Positive charge is because of protons inside nucleus.
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.
Because Joel is the man
no
-The nuclear density being large -most of the atomic volume being empty space -the charge on the nucleus being positive -the existence of the atomic nucleus
John Dalton.. :))
