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!

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.

ReplyDeleteFrom Zachary: Calcium + Oxygen
ReplyDeleteI predict that Lithium, with one valence electron, will give that one up to Chlorine, which has seven valence electrons.
ReplyDeleteLaura
I also predict that oxygen will combine with sulphur, because they both have six electrons in their outermost shell.
DeleteLaura
what about hydrogen and lithium, that would work, wouldn't it?
ReplyDeleteNitrogen +Hydrogen? That could work.

ReplyDeleteCarbon (2-4) and Silicon (2-8-4)
I predict that Argon will combine or share one of its electrons with Chlorine.
