THE MYSTERY
Last unit we discovered that the number of protons determines what an atom is.
But that doesn’t explain how an atom behaves.
Consider:
Sodium is a highly reactive metal.
Chlorine is a toxic, reactive gas.
Put them together correctly and you get…
table salt.
Which you sprinkle on your french fries.
Something about an elements atoms determines whether they react, what they’ll react with and what they’ll become.
Your mission this week:
Through your readings, figure out what determines whether they will react, why they will react and what the reaction will likely be like.
1. Learn
Complete the following in order and please note that here and forever after when I say “read pages… or complete page…” it is referring to your Friendly Chemistry Student Book. Also, you may want to look briefly at section 2 Chemistry Notebook to see what terms (words) to take notes on as you read. I have also included some “assistant” videos to be watched AFTER (aside from the intro video) you do the readings for each section. We hope you enjoy and will have these forever in your chemistry memory. Happy learning:).
INTRO VIDEO:
REVIEW with a little add on. I promise this is necessary.
To get us back into our chemistry mindset, complete the following.
- 1. Electron Configuration Notation: Read pgs. 53-58; Answer questions 1-6 on page 59
- 2. Electron Dot Notation: Read pgs. 61-65; Answers questions 1-6 on page 66. The book does a good example explaining this. The video below explains how to write the dot notations when you have valence shell patterns that cross into eachother, for example Zn. Zn 3d shell layer is indeed in layer 3 HOWEVER it’s little elbow pokes into layer 4, which is why the electronic configuration has 3d AFTER 4s. This video helps you understand how to do the dot notation when that happens. Professor Perkins seeks for dot notation creative expression. He gets repromanded. They are not random dots. Simply a reflection of the valence electrons (or electrons in the outmost layer… also called a shell).
NEW CONCEPTS:
Now that you have electron configurations running through your head, lets see why they are helpful.
- 1. Relating Electron Arrangement to Reactivity: Read pgs 69-78; Answer questions 1-6 on pg. 79. In this video, Professor Perkins refers to the Halogen family as the Hydrogen family. Rest knowing that Professor Perkins is well aware of that, and still feels a credible professor. Even the best can mix up their explanations. Good job Professor Perkins.
- 2. Ionization Energy (Trends of the Periodic Table): Read pgs 81-87. Use this data chart for this section rather than filling in your own.
- 3. Atomic Radius or Atom Size (A Final trend of the Periodic Table): Read Pages 89-93; Answer questions 1-6 on pg 95. Use the chart below for this section rather than completing the chart as indicated.
- 4. Ion Fromation: Read pgs 97-105
- 5. Determining Ionic Charges: Read pgs 107-112;
- 6. Complete the experiments as explained in section 3 (Chemistry in the real world) below.
2. Chemistry Notebook
Continue to take notes as you read each section. Be sure you include the following things:
- Electron configuration
- Valence electrons
- Electron dot notation
- Families/Groups
- Sodium Family and it’s memebers
- Noble gas family (or inert gas family) and it’s memebers
- Halogen Family and it’s members
- Oxygen Family and it’s members
- Calcium Family and it’s members
- Ionization energy
- Electron affinity
- Period (as is used in chemisty)
- Atomic radius
- Atomic radius trends on the periodic table
- Ionization Energy
- Ion
- Cation
- Anion
And most importantly:
- explain in your notes: What do an atom’s outer electrons have to do with it’s chemical behavior?
3. Chemistry In the REAL world
Now for the fun part of chemistry, Licensed Tomfoolery (or in other words… the experiments). Print off the following page and complete as instructed. Have fun!
4. Chemistry and the Armor Of God
This month the topic for the Vanguard theme is: the breastplate of righteousness.
Here’s two thoughts and a challenge for you.
William R. Bradford said, “The word RIGHTEOUSNESS is a most interesting and unique word. It is an umbrella word that spreads out and covers all the attributes of God. A person, then, who is righteous is Godly or Godlike… Righteousness is a composite of all that is good….”
Like a breastplate, righteous acts protect me. When I tell the truth, I am protected from being caught in my own lie. When I choose to keep the word of wisdom, my body is protected from the harmful effects of drugs and alcohol. When I choose to love and respect others my soul is protected from the internal drainage and weight that comes from hate, jealousy, and or bitterness.
There is another way that breastplate of “righteousness” protects us. Did you know that Jeremiah 23:5-6 says: “And this is his name whereby he shall be called, THE LORD OUR RIGHTEOUSNESS.” When I think of the breastplate of righteousness that way, I hear it say, ” take upon you the breastplate of Christs righteousness” to protect you. Meaning, don’t forget that you have a Savior that not only “has your back” when you go into the battles of life (like a breastplate would) but He also protects your heart and sould from the effects of sin as His righteousness can wash your sins COMPLETELY clean if you allow him. He truly can protect you with HIS righteousness.
No one makes it in this life alone. Even one mistake is enough to keep us out of the kingdom of heaven. He can protect our heart from discouragement. Truly, his righteousness becomes our eternal protection.
That is some serious protection from righteousness. That is some serious protection from the LORD.
In a chemistry way, it’s like we are a halogens. We need the lords righteousness to truly be happy. As we combine with him, we step into HIS stability. His nobility. His rest.
So, challenge for the week. What is either one action of righteousness you can bring into your life OR one action of unrighteousness you can repent of to better equip yourself with the breastplate of HIS righteousness? Write it down in your journal and begin!
