You have three elements, A, B, and C, with the following electronegativity values: A = 0.9 B = 3.0 C = 3.5 You react the elements to form the substances AB, AC, and BC. Answer the following questions: What type of substance is AB? What types of bonds are present? Explain your answer. What type of substance is AC? What types of bonds are present? Explain your answer. What type of substance is BC? What types of bonds are present? Explain your answer. If any of the substances are ionic compounds, which element is the cation and which is the anion?

Answer the questions in the table below about the shape of the phosphorus tetrafluoride (PF ) anion. How many electron groups are around the central phosphorus atom? Note: one "electron group" means one lone pair, one single bond, one double bond, or one triple bond. What phrase best describes the arrangement of these electron groups around the central phosphorus atom? (You may need to use the scrollbar to see all the choices.) v (choose one) linear bent T-shaped trigonal planar trigonal pyramidal square planar square pyramidal tetrahedral sawhorse trigonal bipyramidal octahedral O
