Friday's homework

Hopefully, you should have completed your Chapter 18 test yesterday, and put that in your binder to turn in on Monday.  It would be cheating to change the answers now.  Jus' sayin'. Hope you enjoyed the amazing rain.  My street was completely flooded for a while, and the park was a little lake. Quite fun.

Today's homework:
1. Read and study Chapter 19.1 Stability in Bonding, and highlight everything you think is important.  --vocabulary, major concepts --and be able to answer all the questions asked in picture captions.  Study the pictures carefully!   KEY CONCEPT - STABILITY  means stay-bility ...

----And here is a worksheet to help you ---https://drive.google.com/file/d/0B07s3-bcUr7tb0dpSlVKdlZjdHc/view?usp=sharing  {to check your answers, see link below.}

2. Atomic Trading Cards page 579 -- this is what we started in class.  In your SJ,predict which pairs of elements might combine to form stable compounds.  Re-draw those Rutherford-Bohr diagams  in pairs which you predict will combine.  (Like sodium and chlorine) -- Can you find 10 (at least)? In the comments below, write in a combination that you predict will bond to each other.  Everyone different.
  And here is an "answer sheet" --This is what your cards should look like.

3.and some videos: take notes//illustrate in your SJ: (like a page for each video seems right, because pictures take a lot of space)


These videos are so good, you might want to watch them again!

  1. For instance, here is where I predict that beryllium, with two valence electrons, might give up those electrons to oxygen, which has six,. Or that magnesium might combine with two molecules of chloride.

  3. I predict that Lithium, with one valence electron, will give that one up to Chlorine, which has seven valence electrons.

    1. I also predict that oxygen will combine with sulphur, because they both have six electrons in their outermost shell.

  4. what about hydrogen and lithium, that would work, wouldn't it?

  5. Nitrogen +Hydrogen? That could work.
