Bohr Quantum Model Quiz

During a science class, Emma was asked to identify the scientist who proposed the Bohr model of the atom. Can you help her?

• Albert Einstein

• Erwin Schrödinger

• Niels Bohr

• Marie Curie

Isla, Ethan, and Olivia are discussing the Bohr model of the atom. What is the main postulate of the Bohr model that they should focus on?

• Electrons orbit the nucleus in a continuous spiral.

• Electrons orbit the nucleus in specific energy levels or shells.

• Electrons orbit the nucleus in opposite directions.

• Electrons orbit the nucleus in random energy levels.

Mia, Evelyn, and Arjun are studying the Bohr model for their physics class. According to this model, where are electrons allowed to exist in an atom?

• Energy levels or orbits

• Conduction band

• Valence band

• Nucleus

Noah, Abigail, and Emma are studying the Bohr model in their physics class. They learned that electrons occupy energy levels around the nucleus. What is the maximum number of electrons that Noah said can occupy the first energy level in the Bohr model?

• 8

• 6

• 2

• 4

Ethan is studying the Bohr model of the atom and wants to understand the significance of the principal quantum number. What does the principal quantum number represent in the Bohr model?

• The principal quantum number determines the shape of the electron's orbital.

• The principal quantum number indicates the spin of the electron.

• The principal quantum number represents the energy level or atomic orbit of an electron in an atom.

• The principal quantum number determines the atomic number of an element.

During a chemistry class, Maya, Grace, and Ethan were discussing the difference between the Bohr model and the quantum mechanical model of the atom. What is the main difference between these two models?

• Both the Bohr model and the quantum mechanical model do not account for the wave-like behavior of electrons.

• The Bohr model is a simplified model that only works for Hydrogen, while the quantum mechanical model describes electrons as wave-like particles in all atoms.

• Both the Bohr model and the quantum mechanical model describe electrons as wave-like particles in orbitals.

• The Bohr model describes electrons for all atoms, while the quantum mechanical model is a simplified model that only accounts for Hydrogen.

In a science class, Mia, Elijah, and Arjun are discussing the Bohr model of the atom. How does the Bohr model explain the stability of atoms in their discussion?

• The Bohr model explains the stability of atoms by proposing that electrons are stationary and do not move around the nucleus.

• The Bohr model explains the stability of atoms by suggesting that the nucleus is made up of multiple smaller particles.

• The Bohr model explains the stability of atoms by proposing that electrons orbit the nucleus in specific energy levels or shells.

• The Bohr model explains the stability of atoms by stating that the number of protons and neutrons in the nucleus determines the stability.

In a science project, Abigail is studying the Bohr model of the atom. She wants to understand the relationship between the energy of an electron and its atomic orbit. Which electron transition would have the most significant amount of energy?

• n= 6 to n= 2

• n = 3 to n = 2

• n = 2 to n = 1

• n = 3 to n = 1
