Draw the Lewis structure for the BrO3- ion before answering the following questions (You do NOT submit a picture just answer the questions) Bromine is the central atom and all atoms obey the octet rule.   WARNING:  Do NOT USE the internet or other sources  to find the structures. Use ONLY the rules taught in class. ALL atoms obey the octet rule Answer the following questions for the  Lewis structure for the BrO3- ion given that Bromine is the central atom and all atoms obey the octet rule. Give answers as numbers (1,2,3 ...etc.) not words (one, two three etc.) How many bonds does the Bromine atom form  How many electrons surround the Bromine atom  How many lone pairs are around the Bromine atom  How many bonds does each oxygen atom form  How many lone pairs are around each oxygen atom  How many electrons surround each oxygen atom

1. Match the type of bond to the description     2. Which of the following statements are true of metallic bonds?

1. Considering ionic compounds, a) What type of elements tend to form cations and why? b) What type of elements tend to form anions and why? c) What is the formula for aluminum oxide? Describe or show what happened to the valence electrons of each atom to make the compound. 2. Considering molecules and covalent bonding, a) Draw the Lewis structure of SO2 that obeys the octet rule. (Draw this out on paper, take a photo, and embed this image into the document you will submit). b) Label on your structure which electrons are bonding and which are nonbonding. c) What is the molecular shape of this molecule? d) Look up the electronegativities of these two elements in Figure 4.5 of the text. Would you expect this molecule to be polar or nonpolar? Why? 3. What is molecular recognition, how is it used to create medicines and materials, and why is it advantageous to use this in the manufacturing new drugs and medicines? 4. Carbon dioxide in the atmosphere has been a topic in the news lately as…
