Lewis structure practice worksheet with valence electron counts and molecular shapes for common compounds and ions.

A worksheet showing Lewis structures, valence electrons (VE's), bonding electrons (BE's), and lone pairs (RE's) for various molecules and ions, including HCN, C₂H₂, N₂, SO₄²⁻, SO₂, O₃, PO₄³⁻, ClO₃⁻, SF₆, XeF₄, PCl₅, and SeF₄, with some structures labeled as resonance forms and shapes like linear, bent, tetrahedral, trigonal pyramidal.

▼

- The provided Lewis structures for HCN, C₂H₂, N₂, SO₄²⁻, SO₂, O₃, PO₄³⁻, ClO₃⁻, SF₆, XeF₄, PCl₅, and SeF₄ are correct.
- All valence electron (VE's), bonding electron (BE's), and remaining electron (RE's) counts are accurate.
- Molecular shapes are correctly identified for all species except ClO₃⁻, which should be trigonal pyramidal (not "trigonal pyramidal 0").
- For expanded octet molecules (SF₆, XeF₄, PCl₅, SeF₄), the structures correctly show central atoms with more than 8 electrons.
- Resonance structures for SO₂ and O₃ are appropriately noted.
- The task to draw Lewis structures without specifying shape for expanded octet molecules is fulfilled.
