What are Periodic Trends?
(Std 1)
How properties change as you move from one place to another on the chart.
Only 3 trends possible

Mini-Lab - Rules & Directions
1. Work in pairs
2. Go to periodic table being used for this exercise:
At my website: click today's date.
In the "In Class Assignments" section click on the
World Globe link.
3. Remember 3 different trends starting where?
lower left --or-- top left --or-top right
4. When you are done, leave computer on the screen for the
periodic chart from USC.
DO NOT CLOSE THE WEB BROWSER
Be sure to record your computer number
Make origin of each arrow meet.
Then draw diagonal.
10/24/2012 Standards: Std 1 - Structure of the Atom

2. Which atom has the smaller electronegativity?
In or Cl

This Dalek Tesla Coil demonstrates shielding. The
man on the right has a "wire cage" around him that
is connected to a metal stake in damp dirt. This
allows the cage to drain off the electricity before it
gets the man.
Whizzy assignment:
Uses www.mrwiggersci.com/chem
To get the Whizzy Periodic Chart, follow this path in my menus:
Learning Center > Web Helps > Ch 5 > Orbitals > David Whizzy's Periodic Table
1. Tell difference between changes in arrangement of electrons going up
and down a Group in the representative elements vs changes going
left to right in a period. You need to write at least 2 observations of
what you see by clicking on elements in Group 1 of the periodic chart in
both sides.
(Hint: be aware of amounts and
positions of electrons, especially
the 1s electrons )
2. Next you need at least 2 observations of what you see as you click on elements in the 4th Period,
starting at K and ending at Kr.
3. You need 2 observations of what you think is happening when
you change from nuclear view to shell view.

10/25/2012 Standards: Std 1
Objectives:
a. Complete data gathering for Periodic Trends LaB
DO NOW:
1. HW to BASKET
2. Get out your Periodic Trends lab sheet and read it silently to yourself
HOMEWORK:
1. Chapter 6 Assess, p. 174-175 41-55 (5 pts) Std 1
2. Complete all questions for lab and we will discuss tomorrow.
Lab will actually be turned in on Monday
=======================================================
STAMPS: NONE
BASKET: 1. Ch 6 Assess p. 174 26-40 (5 pts) Std 1
We finish lab data gathering tomorrow
We discuss results on Mon
Lab will be due on Tu
Groups on East side of room
Do Data Table C / Procedure first (uses liquid
solutions for tests). Wash and wipe dry well plate.
For all of you, procedures will be in this order:
C ---> (wash well plate) ---> A ---> B --->Clean up.
Groups on West side of room
Do all procedures in order:
A ---> B (wash well plate) ---> C ---> Clean up
Time until clean-up ===>
Return thermometers to right hand island,
not your drawer!!!!!!
Litmus paper - tear into 3rds so you can do 3 tests with each strip
Cleaning well plates - don't push too hard, they will break. If you have
use 1-2 drops of the HCl solution to
remove it. At end of lab, all well plates should be crystal clear.
white stuff that won't come of
Black Paper:
For PROCEDURE C only. Do not use for anything else. Purpose is to be able to see white precipitates in
clear well plates.
Dirty well
plate, needs
HCl
10/26/2011 Standards: Std 1 (structure of the atom)
Objectives:
a. Complete lab
b. return papers
c. fix any problems with grades
DO NOW:
1. Pick up all papers being returned
2. Put homework and journal out on your desk for stamping
3.
THEN
Complete your lab by gathering any data you need from procedures
you have not done yet.
HOMEWORK:
1. Help Sheet for Quiz 2.2 Ch 6 (includes 2-5) - 1/2 of 8.5x11" page, one side only.
2. Complete the questions you can from the lab. You will be able to ask
questions Monday about what data means and how to use that data to
answer lab questions.
