1/24 MS Chemistry update and homework due 1/31
Hi folks,
This week we dove a bit deeper into the periodic table by looking at valence electrons and molecular bonding. We are going to do more of this next class as well. It's a little tricky.
For homework this week, please answer the questions below.
Also!!!!! Go to this website and click on the play button. Have fun playing with the different simulations here. This is a great way to review what we've been working on so far and really solidify the concepts. At the site, you'll see a link that says "game". There are four games here. Play all of them and try to get 4 or better for your score. Please write down the game and the score you got so that I can see that you've tried these. One thing that's tricky about this, the way they do the element box is odd. It took me a while to get the hang of it. I've included a little guide below to help you figure out what's going on. Have fun and good luck!

1/17 MS Chemistry update and homework due 1/24
Hi folks,
Draw Bohr diagrams of the following atoms.
Today we dove even deeper into atomic structure as we learned how to draw Bohr diagrams. These will allow us to see how the electrons are configured in an atom and will allow us to predict how each atom will make molecules.
For homework this week please answer the following questions and do the enclosed worksheet. I've included answers in a .pdf. Be sure to really understand these Bohr diagrams. I smell quiz material….:)
Draw Bohr diagrams of the following atoms.
1. Nitrogen
2. Aluminum
3. Calcium
4. Magnesium
5. Argon
6. Neon
7. Helium

1/10 MS Chem update and homework due 1/17
Hi folks,
During this week and last week's class we spent a good bit of time with the periodic table and reviewed protons, neutrons and electrons. The next few weeks we will be diving quite deeply into the periodic table and the language of atoms and molecules.
For homework this week:
Do the enclosed worksheet. I've included the answer key so that you can check your work. Beware, there are some isotopes and ions on the sheet so pay close attention. This may be a little tricky so take your time on this. I want you to fill out all the blank spaces on the table. Let me walk you through the first one. On the first line, notice that the letter B is on the right hand side. That is the atomic symbol for Boron so look up Boron in your periodic table. Once you've found it, fill in the blanks. For example, atomic number would be 5, protons would be 5, Electrons are 5 and Atomic mass is 5 + 6 so 11. Since some of these are isotopes you want to make sure you add protons and neutrons to get the atomic mass. Also, if you need to find the number of neutrons, be sure to use the atomic mass on the worksheet to find them. It may be a sneaky, sneaky isotope. For the second one, they don't give you the symbol but they do give you the atomic number so you can go from there. Last but not least, look at the 5th one. It says Fe+3. That means it's a positive ion of iron so how many electrons should it have. Be sure to check your answers on this. Please email me if you're confused.
