Final answer:
Step 5 in writing Lewis structures is about assigning remaining electrons as lone pairs to outer and then central atoms to complete their octets or duets for hydrogen.
Step-by-step explanation:
The Step 5 of Writing Lewis Structures with the Octet Rule involves distributing the remaining electrons as lone pairs. You should first complete the octets of the outer atoms and then fill in the central atom's octet, ensuring hydrogen atoms receive no more than a duet of electrons. It's a critical step in achieving stable molecular structures when applying the Octet Rule.
