Q2: Week 6 – Archive
Week of 12/15 – 12/19
12/15 – Monday – period 7/8 –
DOG 4 –
Flame Test Lab Due tomorrow
HW:
1: Complete and hand it Lab 8,9, and 12 due by the latest tomorrow 12/16.
2: I will not accept them after Tuesday. They will be doughnuts.
12/16 – Tuesday – period 7 –
Unit 3 begins – Periodic Table –
1:Dmitri Mendeleev –
2: Periodic table song
3: Trends of the Table
Concepts:
1: Table of elements arranged according to chemical properties (that we now know to be valence electrons).
2: The three trends of the periodic table:
a) Atomic Radii- The size of the atom
b) Electronegativity- The attraction that an element has for (other atoms) electrons.
c) Ionization Energy – The energy needed to pull electrons away from an atom.
3: These three trends are responsible for all of the properties of elements and thus defines elements as Metals, Non- metals and Metalloids.
Today’s lesson:
Mia and the elements : can only play through my channel
HW:
1. Re-watch today’s lesson video (which is a recap of what I did today) if you not understand
everything I did today.
2: Watch Lecture 3.10R – Periodic Table properties with the BlankPeriodicTable[1].pdf worksheet.
3: Fill in the worksheet as directed in the lecture . (RAT 27 tomorrow).
12/17 – Wednesday – period 7,8 –
1: RAT 27 – On Lecture 3.10R
2:Handback Dog 3 & 4 – Review Tests
3: Periodic Table Lab – Please download the following file and save it to your computer.
Concepts on tonights lecture:
1:Metalliods (Semimetals) separate the metals and nonmetals.
2: Metalliods are located on the Staircase in the periodic table
3: TRansitional metals are locate in the middle of the periodic table and are less reactive than the metals that are in group to the left.
4: Metal reactivity increases as the atomic radius increases.
5: Nonmetal reactivity increases as the atomic radius decreases.
6: Most reactive metals are in the Alkali (group or column 1) and the Alkaline Earth (group or column 2).
7: Most reactive nonmetals are in group (column) 17 called the Halogens.
8: The least reactive group is in group (column) 18 called the Noble Gases.
HW:
1: Please watch tonights lecture 3.11R Periodic reactivity & families (RAT 28 tomorrow)
2: Follow along with the periodic table we were started filling in.
3: Make sure you have all three graphs completed for tomorrow in your Excel files.
12/18 – Thursday – period 7-
1: Q/A – Lecture 3.11R
2: RAT 28
3: Periodic people activity (Atomic Radius)
HW:
1: Every one must make 3 posts on the class video of the activity. They must respond to 2 comments acting as the element they became in class.
2: These comments must be appropriate for each elements properties or reactivity.
3: So play the video or open up the video in youtube and post. You must post the following way:
4: We found Waldo!!!!!!!
5: No RAT tomorrow..Excellent job today!
Example of proper post:
Ca (Mr. G): I can’t believe I just lost both of my electrons! Did Waldo take them? Could Waldo take them?
12/19 – Friday – period 7,8 –
