Problem

The key insight here is recognizing that molecular stability depends on whether atoms can form valid electron configurations and satisfy bonding rules. You'll need to think about octet rule violations, formal charges, and whether the proposed bonding is chemically reasonable—some species simply can't exist because the atoms involved can't achieve stable arrangements or the charge distribution is too unfavorable. Check each candidate by counting valence electrons and seeing if a sensible Lewis structure is possible.
