Check the statements that are accurate. Check all of the boxes that apply. Before Thomson’s experiments, scientists accepted that the atom was made up of smaller particles. Rutherford showed that most of the atom’s volume is empty space. After Thomson’s, Millikan’s, and Rutherford’s experiments, scientists generally accepted that an atom contains a small, positively charged nucleus surrounded by negatively charged electrons.

Answer 1) It is incorrect.

Explanation : For the statement;

Thomson did experiments with cathode ray tubes to show that all atoms contain tiny negatively charged subatomic particles called as electrons.

So the statement should be like this:
AFTER the Thomson’s experiments, scientists accepted that the atom was made up of smaller particles.

Answer 2) This is correct.

Explanation : Rutherford was the scientist who discovered that atoms has volume is because of the empty spaces inside it. He did the gold foil experiments to prove this and he was successful in doing this by concluding that tiny dense empty places are occupied by positively charged nucleus.

Answer 3) This is Correct.

Explanation : After Thomson and Rutherford, Millikan also performed an experiment to prove that an atom contains a small positively charged nucleus which is usually surrounded by negatively charged electrons by his oil drop experiment.
