Question

What did Ernest Rutherford’s gold foil experiment demonstrate about an atom?

Each atom is composed of electrons and positive material.
The mass of the atom is evenly spread throughout the atom.
Neutrons are located in the center of the atom.
Positive charge occupies a very small volume in the atom.

Answer 1

I believe its the last one

Step-by-step explanation:

The gold-foil experiment showed that the atom consists of a small, massive, positively charged nucleus with the negatively charged electrons being at a great distance from the centre. Niels Bohr built upon Rutherford's model to make his own.
