Read the following statements. Which ones are correct? Be sure to explain how you know. I. BF; and PFg are examples of exceptions to the octet rule. II. BF," and BF3-NH3 are examples of violations of the octet rule. III. Expanded valence shells occur most often when the central atom is bonded to a small, electronegative element. IV. The central atoms most capable of having expanded valence shells come from rows 3, 4, and 5 of the periodic table.

I know you guys only solve up to three sub parts but plz plz solve it all for me... may you have the best day of your life .. god bless ya
We can draw three inequivalent Lewis structures for the arsenite ion , AsO33- . The concepts of formal charge and electronegativity can help us choose the structure that is the best representation.1. Assign formal charges to the elements in each of the structures below.Note: Count oxygen atoms starting from the left for each structure. A B C Formal ChargeAsO1O2O3 2. The best Lewis structure for AsO33- is (A,B, or C)
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. 00
An incomplete Lewis structure is shown below. The structure only shows the atoms and how they are connected. The molecule has a net charge of zero. H I H-C-C-N-O | H Complete the Lewis structure giving all atoms full octets. If there is more than one way to do this, draw resonance structures showing all possibilities. If not, just draw one Lewis structure. Be sure to write in any non-zero formal charges.
Consider the Lewis structure below. What is the formal charge on Sb? CI CI CI Sb CI CI O a. -2 O b.-1 | O c. +2 O d. 0 O e. +1 е. 29 TOrU 13) 2914
