Apr 20, 2015  · The answer is B) 1. The number of valence electrons is 5 + 3×7 = 26. If you draw a trial structure in which P is the central atom and every atom has an octet, you will have used 26 electrons. This is the correct number of electrons, so the trial structure is the correct structure. The P atom in "PF"_3 has one lone pair of electrons.

STEPS INVOLVED There are three basic steps to determining the molecular shape of a molecule: Write the Lewis dot structure of the molecule. That gives you the steric number (SN) — the number of bond pairs and lone pairs around the central atom.

The older Arrhenius theory of acids and bases viewed them as substances which produce hydrogen ions or hydroxide ions on dissociation. As useful a concept as this has been, it was unable to explain why NH 3, which contains no OH – ions, is a base and not an acid, why a solution of FeCl 3 is acidic, or why a solution of Na 2 S is alkaline. A more general theory of acids and bases was.
