Final answer:
The Lewis electron dot structure for SO2 and its VSEPR shape are described.
Explanation:
Lewis Electron Dot Structure for SO2-: To draw the Lewis structure, we start with the number of valence electrons for sulfur and oxygen. Sulfur has 6 valence electrons, and oxygen has 6 each, totaling 18 electrons. Sulfur is the central atom with a double bond to each oxygen atom and one lone pair, resulting in a total of 18 electrons being used.
VSEPR Shape of SO2-: The VSEPR shape of SO2- is bent/angular. This is because of its molecular geometry, where the lone pair on sulfur pushes the oxygen atoms closer, resulting in a bent shape.
