Homework

If you did not do homework over the weekend (notes for 4 videos and a sketch of the periodic table) make sure you get to it before today’s homework (below).

Below is a little summary of ion formation that results in ionic compounds and ionic bonds.  I put this together to summarize what we learned in class today:

As you have learned before, all of the elements on the periodic table want to be like the noble gases.  They all want to have 8 valence electrons.  They all want eight dots around their lewis-dot structure. 

How do they do that? Well, some can gain electrons in order to become like the noble gas on the periodic table.   Others however, need to lose electrons in order to become like the noble gas.  Let’s look at two examples:

1.Fluorine is a very unstable atom.  It has 7 valence electrons and wants to have eight.  So it gains one electron in order to become like Neon.  When it does, it becomes very happy and stable because it has 8 valence electrons.  But something happens.  It now has 10 electrons and only 9 protons.  It is no longer a neutral atom.  It is now an ION.  An ION with a negative charge. An anion

2.Sodium is also very unstable.  It has one valence electron and wants to be like the noble gases.  It is too far away from Argon on the periodic table and too hard for it to gain 7 electrons.  So Argon tells it to dream on.  

Sodium does not give up and finds another noble gas to mimic.  It finds that it is easier for it to lose an electron and become stable like Neon than it is to gain 7 and become like argon.  And this is exactly what it does.  It tosses out its valence electron.  But something happens.  It now has only 10 electrons but 11 protons.  It is no longer a neutral atom.  It is now an ION.  An ION with a positive charge. A cation.

Flourine and sodium are a good match because F wants one electron and Na want to transfer one.  Because you only need one F for every one Na atom the ionic formula would be NaF.

Next, watch the 2 videos below and take notes (you will need a computer):

Click here to watch video on ionic bonding

Now, use what you have learned to complete the questions below (in your notebook).

1.       Explain why all elements in group 18 (or 8) are relatively unreactive whereas their neighbors, elements in group 17 (or 7), are highly reactive?

2.       Which of the following correctly compare and contrast the ways in which metals and nonmetals form ions

a.        Metals lose electrons and nonmetals gain electrons

b.       Metals gain electrons and nonmetals lose electrons

c.        Both metals and nonmetals gain electrons

d.       Both metals and nonmetals lose electrons

3.       Which is not true regarding sodium ion?

a.        It forms a positive ion

b.       It has a charge of +1

c.        It has lost an electron

d.       None of the above

4.       Show how Sodium and Iodine form ionic compounds using one of the two methods we learned in class.

5.       Show how Magnesium and Oxygen form ionic compounds using one of methods we learned in class.

6.       Predict whether each of the following elements will come together to form ionic bonds.

      • potassium and Sulfur
      • lithium and oxygen
      •  beryllium and aluminum

 

7.       How many electrons do the following ions have?

Sodium ion with a charge of positive 1

Chlorine ion with a charge of negative 1

Holiday Chemistry Packet

This Holiday Chemistry Packet will help you become an expert on your element and develop the necessary skills to produce your documentary.  If you still have not chosen your element, please click here.  Make sure you follow all of the instructions.  Project Guide and Rubric available on main page.

  1. You will need to learn about your element and demonstrate your understanding.  There are 3 interactive periodic tables on own main page (interactive periodic table, periodic videos and periodic table-fun facts).  You will need to click on your specific element and actively read or watch the information provided.  Include notes in your metacognitive log.  This part will need to be completed prior to January 3rd.  
  2. Must be completed by January 4th (you may do this before the 4th): Click on ‘Choose your Element’ on our main page.  And within the forum go to your initial post.  Summarize what you have learned about your element in at least 2 paragraphs.  What are the chemical and physical properties? What makes it so interesting? Is it useful? how? Click on ‘reply’ to do your writing.
  3. Must be completed by January 6th (you may do this before the 6th): Read over some of your classmates writing and reply to at least 2 different posts using at least a complete paragraph (5 sentences).  What did you find most interesting about their element?  What are some similarities and differences between your element and their element?  What else would you like to learn about their element and what other information do they need to include that you feel might help their documentary.
  4. Click on ‘Project Guide and Rubric’ on the main page.  Make sure you have all of the guiding questions completely answered in your metacognitive log.  Read over what your classmates might have posted about your element.  Organize all of the information that you want to go into your video on a flow map
  5. Produce your video, upload to YouTube and link to your eportfolio “the development of the atomic model”.

Homework

For today’s homework you will work to select your element (this element will be the focus of your documentary) and begin the research that pertains to your specific element.

I have uploaded 3 interactive periodic tables that you may find very useful.  They are very helpful in helping you learn more about your element.

The interactive periodic tables and periodic videos as well as the link that will allow you to choose your element are on our main page.

No two people in the same class can choose the same element for their project/documentary.  

To select your element and confirm that no one has chosen it, click on ‘choose your element’ on the main page.  In order to select and secure your element you must do the following things (1st come 1st serve):

  1. Click on ‘add new discussion topic’ in the discussion forum titled ‘select your element’.
  2. In subject write the following: The name of the element of your choice and the correct symbol.
    • For example, if I want to choose Argon, my title would be: Argon/Ar
    • Do not put your name in because it will come up automatically. 
  3. you must also include the following things about your element in the message box:
    1. The state or phase of your element at room temperature
    2. how many protons,electrons and neutrons it has
    3. A few pieced of information
    4.  fun fact.
  • If you don’t follow the procedure above, your name will be automatically removed and someone else will be able to choose your element and you would need to reenter your selection and possibly with a different element.

It’s only fair that the first person to get to select that element should know a little bit about it.  Make sure to scan the different discussion topics and if someone has selected the element of your choice then you need to choose another element.  First come first serve.  

Have fun!!  🙂 

There are 3 interactive periodic tables on the main page that you can use for selection and research.

Homework

2nd and 3rd hours will complete numbers 1 and 2  below, 4th and 5th hours will only complete number 2.

  1. Go to the ‘quantum mechanical model of an atom’ on the main page, watch all 4 videos and take notes.  Then, write your argument (claim, evidence, reasoning) which explains how the particle/wave duality of an electron helps to explain the macroscopic behavior of matter.
  2. Go to your eportfolio page ‘the development of the atomic model‘ and add a ‘reflection piece‘ for today’s homework.  You don’t have to share your page with me again, because I will be able to see any changes you make.  Your reflection piece should consist of the following:
    • What you previously thought about the atom and what you had originally argued in your essay
    • What you now believe and include the new pieces of evidence that brought about that change in your thinking.
