Today we reviewed some of the concepts in the circulatory system, measured our heart beats, our blood pressure and listened to our hearts.
We started off the respiratory system by doing a short labelling/diagram assignment

Chemistry 11
Today we wrote our test on Atoms and the Periodic Table........are you happy that we won't be talking about ionization energy again for a while??
We completed lab 12A by looking at melting times for each of our compounds:
NaNO3 = long melting time
MgCl2 * 6H20 = long melting time
C6H12O6 = short melting time
C12H22O11 = short melting time
KI = long melting time
This lab is due on Friday with Questions #1-3 and Follow-up #1 and Conclusion

Chem 11
If you are gone from Chem 11 on Tuesday May 9th for track we will work on our Unit 5 Review as well as doing the following:
For each Family listed below, pick 3 elements from the family and 1) write their electron configurations, 2) Describe the appearance of the element 3) List the most important uses 4) What is it's natural abundance and how 5) watch the video for each element and give me some new/interesting facts you learned. Use MY FAVORITE WEBSITE to do this. Found HERE 6) Explain what common properties these elements all have.
Families: Alkai Metals, Alkaline Earth Metals, Transition Metals, Halogens, Noble Gases, Lanthanides.

Today we finished off the circulatory system with Power point notes on Capillary Exchange, Lymphatic System, Fetal Circulation and Circulatory diseases.
Due next class: Module Questions C: #1-3 and 5-6
Module Questions G: #1-5
Use the lymphatic system from your text (pg. 235) to help you here.

Chemistry 11
We went over a few questions from the Lewis Dot Diagram worksheet.
Next we looked at the difference between valence electrons and an atom's valence.
Unit 5 Review is due on Wednesday. We will work on it tomorrow.

BIG UNIT 5 Review Assignment. Answers to selected questions.
1. Definitions: You are on your own! Make sure you know the difference between polar and non-polar covalent bonds as we didn't go over these in detail.
3. In any energy level: electrons are added in the following order: s, p, d and f.
4a) Protons=86 electrons=86 neutrons=136
4c) Protons=92 electrons=92 neutrons=142
4e) Protons=27 electrons=24 neutrons=631
5a) [Ar]4s23d10
5c) [Xe]6s24f145d106p2
5 h) Mn+2= start with Mn=25 electrons. [Ar]4s23d5 Take off 2 electrons. So it becomes [Ar]3d5 (electrons are removed from energy level 4 first).
7) Masses are the periodic table are not whole numbers since the mass represents the average atomic mass of ALL the isotopes of that element.
8a) Across a period on the table, atomic radius decreases since electrons are being added to the same energy level. Protons are also added as you go across a period. The attraction between protons and electrons increases as you go across a period, so the atoms "shrink" in towards the center.
9b) Down a group on the periodic table, ionization energy decreases since energy levels are being added with each new group. Electrons are getting further from the nucleus and therefore getting easier to remove.
10) We will discuss this one in class.
11a) Rb has a larger radius than I since electrons are added to the same energy level as you move across. It has more electrons and more protons pulling them in.
12a) Ne has greater ionization energy than Ar. Ne has outer electrons which have a greater pull towards the nucleus.
13a) C= greater electronegativity. Pull of its electrons is greater since it has less energy levels than Si.
14a) P is more reactive than As. P has greater attraction for electrons therefore can pull off electrons more easily from another element.
15) valence electrons are the most important in bond forming.
16) We will go over some of these.
17a) non-polar covalent bond 17c) ionic bond 17e) covalent bond (non polar)
