Answer the questions in the table below about the shape of the bromine trifluoride (BrF3) molecule. How many electron groups are around the central bromine 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 se electron groups around the central bromine atom? (You may need to use the scrollbar to see all the choices.) 0 (choose one) 5 0/3With regard to resonance structures that are drawn for a real species, which of the following statements is NOT TRUE? Select one: O A. Resonance structures are not real; they are only drawn structures. O B. The real species rapidly oscillates between the resonance structures, O C. Resonance structures differ in the location of their electrons, not the positions of their atoms. O D. Resonance structures all have electron localized structures, while the real species that is described by them has delocalized electrons..9.

- A student is using the Lewis model of bonding to determine ways to predict bond types from Lewis structures. A Na: Ci : :NE N: B Which of the following parts of the model are best suited for predicting bond types shown above? O Part A and C, because it is showing charged particles from transferring electrons and therefore ionic. Part B and D, because it is describing a triple bond exist and therefore forming an ionic compound. Part A and C, because it is showing a sharing of the electrons by making an anion and cation. へ 58°F Clear K 99+ ト fs & 2$4 R Y. 00AlpQLSfilrQiXNMT6GPzW_W_SBsP5AkYmSHrHcGFU8zxJynmv0AJCw/viewform?hr contaminatio..
