Draw the Lewis structure for PO3-. What is the molecular shape of a PO3-molecule?

Answer

The Lewis electron dot arrangement must be understood in order to determine the shapes of molecules. Since the Lewis theory does not specify molecule shapes, it is the first step toward predicting molecule shapes. The Lewis structure assists in the detection of bond pairs and lone pairs. The molecular geometry are then determined using the valence-shell electron-pair repulsion (VSPER) theory and the Lewis structure.

The Lewis structure of PO3 is,
