Question 1

The image shows three atomic orbitals, each with the same shape but increasing in size from left to right. Which set of quantum numbers best describes these orbitals in the order shown (left to right)?

Accepted Answer

$$2p,\ 3p,\ 4p$$

Question 2

Which quantum number is primarily responsible for the increasing size of the orbitals shown in the image?

Accepted Answer

The principal quantum number $$n$$

Question 3

If the orbitals shown in the image are all $$p$$ orbitals, how many total $$p$$ orbitals exist for a given principal quantum number $$n$$?

Accepted Answer

3

Question 4

Which of the following statements best explains why the orbitals in the image increase in size from left to right?

Accepted Answer

The principal quantum number $$n$$ increases, increasing the average distance from the nucleus.

Question 5

Which of the following best describes the nodal structure of the orbitals shown in the image?

Accepted Answer

Each orbital has one planar node passing through the nucleus.
