(a)
Interpretation: The electron dot structure for the substance is to be drawn.
Concept Introduction: If the compound's molecular formula is known, electron dot structures or the Lewis dot formulas can be drawn. The type of bond and the location of the atoms in a molecule that are related to one another are determined by the electron dot structure.
