For the diagram that was on the review sheet (the diagram can be found on the second video: finding the valence electrons)...
1. The number of valence electrons was 4. Remember the number of valence electrons are the electrons on the last orbital shell.
2. The number of electrons in total was 6. You had to also count the electrons that were on the first orbital shell.
3. The number of protons was 6 and the number of neutrons (for the purposes of our class) is 6. Remember that the # of protons = # of electrons = # of neutrons.
4. The atomic number is ALWAYS = to the # of protons, which in this case was 6. So the atomic number is 6.
5. Looking at the periodic table, the eleme
I will be posting a video tonight that will review mass and particle charge. We will requiz on Tuesday INCLUDING the atomic structure. Please review the study guide that is on the website and know the names of the different parts.
The grade on Tuesday will be averaged into the grade that was received on the quiz.
If you received a 7/11 (7 divided by 11, multiplied by 100% = 64) and then get an 11/11 (11 divided by 11, multiplied by 100% = 100), your average score will be those two scores (100 + 64 = 164) divided by two (164/2) or an 82.
If you received an 11/11 (100%), you will work on an extra credit assignment on Tuesday that will give you +5 points.
The study guide for you is on this website, under documents and resources.
Our Periodic Table of Elements is almost finished. We still have some elements that need to go up. If you were absent from class on Friday, make sure you come to me during lunch tomorrow with your information. I hope to get it all finished for Parent-Teacher conferences on Wednesday!!
The atomic model project is to be done at home.
I gave out your elements today- so remember what you need to bring with you on Friday! Our periodic table will be created on the bulletin board outside room 110.
For help with building your atomic structure, check out some of these resources:
Answers for the volume worksheet:
1) 210 mm^3 (to the third)
Answers for the density worksheet:
1) mass= density x volume
volume = mass divided by volume
3) 1.76 (g/mL)
4) 136.29 g
6) 16.51 cm^3
8) 2.34 (g/m
Take your time in understanding how to create data tables, scale a graph and plotting your data points.
The homework I gave you over the weekend will definitely help and I'd practice with the graphing HW we did over the past couple weeks (on Friday.)
REVIEW SESSION ON MONDAY AND TUESDAY
We will discuss the textbook homework on Monday, along with data tables and scaling. Make sure to bring a pencil and your completed homework!! Bring your lunch and get there on time!
We will also discuss any key ideas that you missed on Tuesday, along with plotting points on a graph. Make sure to bring a pencil and any issue you have with the review sheet. The review sheet is on the wizard and online.
If I have a lot of students there for review, I may pair you up with someone who understands the concept. This is not because I don't want to help you, rather that I will be spread thin, answering questions and explaining concepts.
USE THE REVIEW SHEET.
