No class today due to assembly.

We learned how to draw Lewis diagrams of compounds with covalent bonds.  Refer to p.75, 81-82 for help with this material. 
Homework:  complete the questions from the "Formation of Ionic Compounds" note; answer p.78 #5; p.81 #7; p.82 #8-10

We discussed the reason for the trends in atomic radius, ionization energy, and electron affinity, using the handout "trend explanations" found on the unit 1 page of this site.  Consult p.52, 55, 58 for help with this explanation.
We also discussed how ionic compounds form, using Bohr diagrams.  The handouts used, "ionic comp handout" and "Lewis diag handout" are downloadable from the unit 1 page of this site.  Consult the text p.75 and 46 for help.
Homework:   p.46 #6

Refer to p.49-54 in the text for help with this work.
If you wish to have the notes ready for tomorrow's class, so that there is less writing to do, then print out "ioic comp handout" and "lewis diag handout" from the unit 1 page of this site.
Homework:  p.52 #7; p.55 #8, 9; p.60 #2-4

We marked each others lab reports and handed them back.  We recorded the trends for metals and nonmetals that we have learned over the past two days.  We recorded patterns in Bohr diagrams in the periodic table.
Homework:  Revise your lab report to hand in to your teacher on Tuesday.

We performed an experiment to observe some metals and their reactions.  Use thechecklist for the lab report to make sure you have everything required.  You are expected to be able to analyse data related to the properties of elements to identify trends in the periodic table.
Homework:  complete the lab report for Monday

We watched a lab safety video.  The link to it is on the Unit 1 page of this site.  You can also download a copy of the lab safety handout from that page, and the lab report format handout. 
You are expected to be able to carry out investigations using the materials and equipment in a safe manner.
Homework:  Answer the questions at the bottom of the lab safety handout;  read p.25-28 and answer p.29-31 #1, 3, 13;  read p.41 and answer p.42 #2.

"Periodic" means repeating in an identifiable pattern.  Today, we examined some of the periodic properties of elements.  The handout used, "Family Properties", can be downloaded from the unit 1 page.  You are expected to be able to analyse data related to the properties of elements to identify trends in the periodic table.  Read text when you get one, p.11, 12.
Homework:  Answer p.39 #1-5

Welcome to Chemistry!  Course overviews are on the science department website, ololscience.weebly.com.  Please view the one for this course with your parents, sign the confirmation sheet, and fill in the parental contact information to hand in tomorrow. 
Expectation for the lesson:  Explain the relationship between the atomic number and the mass number of an element, and the difference between isotopes and radioisotopes of an element.
We reviewed the Bohr model of the atom, isotope symbols, Bohr diagrams and the terms "isotope" and "radioisotope".  Please complete Bohr diagrams for the first 20 elements for tomorrow.  The handouts are on the unit 1 page of this site, and are called "Bohr model review" and "Bohr diagrams"
