16. What is the molecular geometry of PH3? (A) Trigonal planar (B) T-shaped (C) Trigonal pyramidal (D) Tetrahedral 17. The correct Lewis structure for BF3 would have exactly: (A) 1 double bond (B) 2 double bonds (C) No double bonds (D) 1 triple bond 18. Nitrogen has a greater first ionization energy than phosphorus. What is the best evidence to support this observation? (A) Nitrogen has a greater effective nuclear charge. (B) A nitrogen atom is larger than a phosphorus atom. (C) The electron ionized from nitrogen is in a lower energy level closer to the nucleus. (D) The electron ionized from nitrogen is not from a valence energy level.
