The phosphonium ion, PH⁺₄ is formed by reaction of phosphine, PH₃ , with an acid. b. Predict its molecular geometry.

The sulfite ion (SO₃²⁻) and sulfur trioxide (SO₃) have the same chemical formulas but different molecular geometries. Draw the Lewis dot structures and identify the molecular geometry of each.

Choose the shape (1 to 6) that matches each of the following descriptions (a to c): 1. linear2. bent (109°)3. trigonal planar4. bent (120°)5. trigonal pyramidal6. tetrahedralb. a molecule with a central atom that has four electron groups and three bonded atoms

Compare the Lewis structures of CF₄ and NF₃ Why do these molecules have different shapes?
