Chapter 4 Quantum Model Atom Quiz Sections 2 & 3

How does the Quantum Model of the Atom differ from the Bohr Model?

• The Quantum Model describes the location of protons in an atom, while the Bohr Model depicts the location of electrons .

• The Quantum Model and the Bohr Model are the same and can be used interchangeably.

• The Quantum Model describes the probable location of electrons in an atom as a fuzzy cloud with different shaped sublevels, while the Bohr Model depicts electrons orbiting the nucleus in specific orbits.

• The Quantum Model shows the exact location of electrons in an atom, while the Bohr Model is a 3D representation of the atom.

Explain the four quantum numbers and their significance in describing an electron in an atom.

• The four quantum numbers describe the color, size, weight, and speed of an electron in an atom.

• The four quantum numbers describe the energy, shape, orientation, and spin of an electron in an atom.

• The four quantum numbers describe the taste, smell, texture, and sound of an electron in an atom.

• The four quantum numbers describe the temperature, density, pressure, and volume of an electron in an atom.

Explain the Pauli Exclusion Principle and how it relates to the quantum numbers.

• The Pauli Exclusion Principle only applies to protons and neutrons, not electrons.

• The Pauli Exclusion Principle allows exactly two electrons in an atom to have the same set of four quantum numbers.

• The Pauli Exclusion Principle states that no two electrons in an atom can have the same set of all four quantum numbers.

• The Pauli Exclusion Principle states that electrons in an atom can have an infinite number of quantum numbers.

How does the Aufbau principle help in determining the electron configuration of an atom?

• By following the order of filling the orbitals from lowest to highest energy levels.

• By filling the orbitals from highest to lowest energy levels

• By randomly assigning electrons to orbitals

• By ignoring the energy levels of the orbitals
