Presentation transcript:

1. Calculate and record your Chapter # 4 Test % grade. 2. Did you meet your goal? Why or why not. 3. Study (preparation) Plan for next test? 4. Your new goal must be:  same if you did not meet it  at least a 1 point improvement Day

Day How is the periodic table organized and what does it tell you about each element? Work with the group you sit with and come up with as many explanations as possible (contest)!

How is the periodic table arranged?

Atomic number = # of protons = # of electrons (neutral atom) Atomic mass Carbon has an atomic number of 6, which means it has 6 ________ in its nucleus and 6 __________ orbiting around the nucleus. protons electrons

Organization of Your Periodic Table He, Ne, and Ar are in the same ___________. C, N, and O are in the same ___________. P E R I O D S GROUPSGROUPS

Organization of Your Periodic Table Atomic mass *** Atomic # *** Similar properties: Reactivities Electron Configurations (groups) Families

PRELAB

Day elements in the same group = … 2.3 elements in the same period = … USE YOUR NOTES FROM YESTERDAY IF NEEDED!

Day Gaviscon prelab must be handed in before you leave!!!!

Day Carbon, silicon, and germanium are in the same _______ (group OR period). USE YOUR NOTES FROM LAST WEEK IF NEEDED! group

Day GET OUT YOUR LAB!!! 2.How did you describe what happened? Each time the Gaviscon either ____ or ____.

Gaviscon Lab Completed lab packets are due before you leave today or at the beginning of class tomorrow!!!

Day What do lithium (Li), sodium (Na), and potassium (K) all have in common? Think of the lab and/or use your periodic table!

Gaviscon Lab Completed lab packets are due NOW!!!

Day What do calcium (Ca), strontium (Sr), and barium (Ba) all have in common? Think of the lab and/or use your periodic table!

Name _________________________ Page

Day Where are the transition metals on the periodic table? Use your colored periodic table if needed!

metalloids

Get out your color coded periodic table!!!

Metals Excellent conductors (Sea of electrons) even as solids Mobile electrons Metals are malleable and ductile Can be pounded into sheet Can be pulled into wire

Alkali Metals Similar properties: Group # 1 Reactive Good Conductors

Alkaline Earth Metals Similar properties: Group # 2 Reactive – but less than alkali Good Conductors

Noble Gases Similar properties: Group # 18 NON-reactive Gases Full outer shells!!!
