Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Ernst Rutherford discovered which part of the atom throught the use of gold foil?

A	Proton
B	Neutron
C	Electron
D	Orbitals

Explanation:

Detailed explanation-1: -Rutherford’s gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus. Based on these results, Rutherford proposed the nuclear model of the atom.

Detailed explanation-2: -Rutherford used gold for his scattering experiment because gold is the most malleable metal and he wanted the thinnest layer of metal. The gold sheet used was around 1000 atoms thick. Therefore, Rutherford selected a gold foil in his alpha scattering experiment.

Detailed explanation-3: -How was Proton Discovered? In a gold foil experiment, Rutherford bombarded alpha particles on an ultrathin gold foil and then detected the scattered alpha particles on a zinc sulphide (ZnS) screen. According to Rutherford’s observation, Most of the alpha particles were not deflected; they passed through the foil.
