Quantum Numbers Quiz

This shape is that of a...

• s orbital

• d orbital

• p orbital

• f orbital

Answer explanation

The correct choice is a p orbital, as the shape depicted matches the characteristics of a p orbital in atomic structure.

The principle quantum number, n, represents the:

• spin value

• suborbital value

• energy level

• magnetic value

Answer explanation

The principle quantum number, n, represents the energy level of an electron in an atom.

Which of the following is NOT a possible pair of quantum numbers?

• 2p

• 2d

• 4p

• 4f

Answer explanation

The correct choice is 2d because 'd' orbitals do not exist in the second principal energy level, making 2d an impossible pair of quantum numbers.

What does the 1 in "1s" stand for?

• energy level

• s orbitals

• p orbitals

• the number of electrons

Answer explanation

The 1 in '1s' stands for the energy level, indicating the first energy level in the electron configuration.

There may be a maximum of ____ p orbitals at a given energy level.

• 2

• 6

• 3

• 8

Answer explanation

The correct answer is 3 because there can be a maximum of 3 p orbitals at a given energy level based on the Aufbau principle and the maximum number of electrons that can occupy each orbital.

What is the electron configuration for F?

• 1s2 2s2 3p5

• 1s2 2s2 3d5

• 1s2 2s2 2p5

• 1s2 2p5

Answer explanation

The correct electron configuration for F is 1s2 2s2 2p5, as fluorine has 9 electrons distributed across the 1s, 2s, and 2p orbitals.
