Question Description

1) In this lesson, you learned about ionic bonding and ionic compounds. Now, you will demonstrate your understanding of the concepts by responding to the following questions. Make sure you are using complete sentences and showing your work where necessary. First, describe the difference between ionic and molecular compounds in terms of the basic units that make up each. Then, do the following: Draw the Lewis structure for Li2S, Rb2S, and K2S. Then list these three compounds in order of increasing lattice energy. *Pictures from internet sources will not be accepted, all drawings must be completed by the student* "Make sure to show your work, and your answers should be provided with the correct amount of significant figures." YOU WILL RECEIVE A SCORE REDUCTION IF THE ABOVE REQUIREMENTS ARE NOT MET.





2) In this lesson, you learned about how metal electrons move, metallic properties, and metallic bond strength. Now, you will demonstrate your understanding of these concepts by responding to the following prompt. Create a three-slide PowerPoint presentation that describes the electron-sea model of metallic bonding and the relationship between metallic bond strength and enthalpy of vaporization. Your PowerPoint should include graphics. Make your language simple, as if you are explaining these ideas to someone with no prior knowledge of these concepts or chemistry in general. YOU WILL RECEIVE A SCORE REDUCTION IF THE ABOVE REQUIREMENTS ARE NOT MET.






3) In this lesson, you learned about Molecular Geometry, VSEPR Theory, and hybridization. Now, you will demonstrate your knowledge of these concepts by responding to the following prompt.

Draw the Lewis structure and predict the molecular geometry of the following molecules:

a. SO2

b. CI4

c. BCl3






4)

In this lesson, you learned about chemical names and formulas. Now, you will demonstrate this knowledge by responding to the following prompt.

Now:

Draw the Lewis structure, give the name, and predict the VSEPR geometry of H2O, NH3, and SF6.

*Pictures from internet sources will not be accepted, all drawings must be completed by the student*
