Week 2 Discussion

Atomic Structure

Required Resources

Read/review the following resources for this activity:

Textbook: Chapter 3, 7, and 8

Unit 2 Lesson

Initial Post Instructions

Option 1:

Your initial post in the discussion this week consists of two parts. First, choose a molecule used in healthcare, industry, or found in a natural source and discuss the importance of this molecule. Be sure to include at least one outside source and make sure to follow APA citation guidelines.

In the second part of your initial post, we will be practicing naming ionic and covalent compounds as well as polyatomic ions. To begin, give the chemical formula for each of the following: A covalent compound containing no more than two types of elements, an ionic compound no more than two types of elements, and an ionic compound containing a polyatomic. Be sure that these compounds are valid (for example, the charges balance out in the ionic compound) and that the subscripts do not exceed 10.

Option 2:

Your initial post in the discussion this week consists of two parts. First, choose a molecule used in healthcare, industry, or found in a natural source and discuss the importance of this molecule. Be sure to include at least one outside source and make sure to follow APA citation guidelines.

The electron configuration of an atom determines the number of electrons available to participate in bonding with another atom. One method of depicting the valence electrons that an atom has is through the Lewis structure. For the second part of your initial post, pick an element from the periodic table of elements. Identify the valence electrons and the orbitals in which they reside.

Follow-Up Post Instructions

Respond to at least two peers or one peer and the instructor. Further the dialogue by providing more information and clarification. Here are some suggestions for how you can add to the discussion and explore the unit 1 content in more detail:

Respond to a peer's option 1 post and research/discuss one of their chemical compounds. Using the naming rules we learned in class, walk us through each step.

Pick a peer's option 2 post and answer each of the following questions:

How many unpaired electrons are present?

How many covalent bonds could this element make?

Could this element participate in a double or triple bond? Why or why not?
