Models of the Atom Quiz

Who proposed the Bohr model of the atom?

• Niels Bohr

• Erwin Schrödinger

• Marie Curie

• Albert Einstein

What is the main difference between the Rutherford model and the Bohr model of the atom?

• The Rutherford model does not explain the emission spectrum of atoms, while the Bohr model does.

• The Rutherford model describes the atom as a solid, while the Bohr model describes it as mostly empty space.

• The Rutherford model does not account for electron energy levels, while the Bohr model does.

• The main difference is the description of electron orbits.

Which model of the atom suggested that electrons are embedded in a positively charged sphere?

• Bohr model

• Rutherford model

• Dalton model

• Plum Pudding model

Who discovered the neutron?

• James Chadwick

• Isaac Newton

• Albert Einstein

• Marie Curie

What was the purpose of the gold foil experiment conducted by Rutherford?

• To study the properties of gold

• To investigate the structure of the atom and determine the presence of a dense, positively charged nucleus.

• To determine the atomic weight of gold

• To investigate the behavior of electrons in gold

In the Bohr model, what are the energy levels of the electrons called?

• shells or orbitals

• layers

• bands

• rings

Which model of the atom proposed that electrons move in specific orbits around the nucleus?

• Rutherford model

• Thomson model

• Bohr model

• Dalton model

Who proposed the plum pudding model of the atom?

• Ernest Rutherford

• Niels Bohr

• Max Planck

• J.J. Thomson

What did the gold foil experiment reveal about the structure of the atom?

• Atoms have a small, dense, positively charged nucleus at the center, with neutrons orbiting around it.

• Atoms have a small, dense, positively charged nucleus at the center, with electrons orbiting around it.

• Atoms have a large, dense, positively charged nucleus at the center, with electrons orbiting around it.

• Atoms have a small, dense, negatively charged nucleus at the center, with protons orbiting around it.

What is the charge of a neutron?

• 0

• 1

• 2

• -1
