## 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).

BlankPeriodicTable[1].pdf

12/17  – Wednesday – period 7,8 –

1: RAT 27 – On Lecture 3.10R

2:Handback Dog 3 & 4 – Review Tests

Periodic Trends Excel 3 graphs 2012 student file.xlsx

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)

#### Alkali Reactivity

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 –
