Rutherford's Gold Foil Experiment

Which of the following is/are conclusions based on Rutherford’s gold foil experiment?

• Atom is mostly empty space

• The nucleus is positively charged

• The atom has a small dense nucleus

• All answers are correct

Rutherford's gold foil experiment provided evidence that...

• negative and positive charges are spread evenly throughout the atom.

• alpha particles have a positive charge.

• gold is not a dense as previously thought.

• there is a dense positively charged nucleus at the center of an atom.

The Rutherford experiment concluded that

• All alpha particles fired through the gold foil

• The electron cloud is large and positively charged

• An atom barely has any empty spaces

• The nucleus is tiny and heavy compared to the rest of an atom

Rutherford's experiment that he used to discover protons and the nucleus.

• gold foil experiment

• cathode ray experiment

• neither of these is correct

Rutherford's gold foil experiment provided evidence that...

• negative and positive charges are spread evenly throughout the atom.

• alpha particles have a positive charge.

• gold is not a dense as previously thought.

• there is a dense positively charged nucleus at the center of an atom.

Which experiment led to the discovery of the nucleus?

• Thomson's Cathode Ray Experiment

• Rutherford's Gold Foil Experiment

• Chadwick's Neutron Experiment

• Dalton's Atomic Theory

Ruthford's experiment showed that atoms are mostly​ (a)   .

• empty space

• fake

• gold

• lasers

• small

Why did Ernest Rutherford and his colleagues perform the Gold-Foil Experiment?

• They wanted to test and confirm the Plum-Pudding model

• They wanted to test John Dalton's Model

• They were looking for electrons

• They wanted to come up with their own Atomic Model

Based on Rutherford's model of the atom, electrons in the atom are located

• inside of the nucleus of the atom

• outside and around the nucleus of the atom

• outside and inside of the nucleus of the atom
