Problem: Construct electron-dot diagrams for (a) the ammonium ion; (b) carbon tetrachloride; (c) the hexafluorosilicate ion, SiF62-; (d) the pentafluorosulfate ion, SF5-.

FREE Expert Solution

The problem asks us to draw the Lewis Structures (also known as electron-dot structures) of the given molecules: 

ammonium ion (NH4+), carbon tetrachloride (CCl4), hexafluorosilicate ion (SiF62-)and sulfur pentafluoride ion (SF5-).


To do this, we must follow these general steps:

Step 1. Calculate the total number of valence electrons.

Step 2. Determine the central atom in the molecule.

Step 3. Draw the structure for the molecule.

Step 4. Determine the formal charge of the atoms in the molecule.
