Which of the following models of the atom was supported by the gold foil experiment? a. solid, dense sphere b. plum pudding model c. nuclear model d. planetary model

C. nuclear model

Explanation:

In gold foil experiment we know that highly energetic alpha particles incident on gold nucleus then the observations are as following

1) most of the alpha particles moved out without any deviation

2) few of the alpha particles are those which slightly deviated.

3) very small alpha particles i.e. 1 out of 10000 are those which are reflected back by 180 degree.

So above observations concluded that

most of the part of atom is vacant and its whole positive charge is concentrated in a small part which is known as nucleus.

So here this model is known as

C. nuclear model

fgravity=10x10=100n case 1

fgravity=30x20=600n case 2
