Final answer:
The question concerns electron placement in p orbital sublevels according to Hund's rule, which dictates that the sixth electron will have the same spin as the fifth and be placed in the second p orbital.
Step-by-step explanation:
The student's question involves the linear arrangement of electron orbitals according to Hund's rule. Specifically, it concerns the placement of electrons within the p sublevel orbitals following the 2s sublevel in an atom. Hund's rule states that the sixth electron enters the second of the three p orbitals (designated as 2p) after the first three electrons have each filled one of these orbitals singly. Notably, the fifth and sixth electrons will have the same spin when this configuration is reached.
In the context of electron orbital diagrams, when arranging electrons, it is essential to remember to draw all three p orbitals even if one remains unoccupied. This visualization helps ensure that we adhere to the proper electron configuration and Hund's rule, significantly impacting the atom's chemical properties.
