Today we are going to focus on the Periodic Table!

• Activating Strategy…– BRAINPOP!

A Beautiful Mind

This crazy looking man is Russian chemist DMITRI MENDELEEV.

Mendeleev created the first Periodic Table in 1869.

So why is the PToE important?

•ORGANIZATION.– There are a lot of elements on earth. If we

don’t know anything about them/what they have in common, we can’t understand them.

THINK, PAIR, SHARE: (2 minutes) Think back to the end of Earth’s History. We learned about another system of organization that scientists use. What was that system and what did it do? HINT: Think evolution!

So how is the Periodic Table organized?

• Vertical Columns = groups• Horizontal Rows = periods

Your periodic table already has the groups (those gray boxes I told you not to color), let’s label the periods.

Each element lives with its own Family

• Elements on the periodic table can be grouped into families based on their chemical properties.

• Each family has a specific name to differentiate it from the other families in the periodic table.

• Elements in each family react differently with other elements.

1 Week til THXGIVING! 11/15/2012

DO NOW!1. Find the element and identify its family:

- Group 6, Period 5- Group 5, Period 4- Group 17, Period 2- Noble gas with atomic symbol “Ne”- Transition metal with atomic symbol “Ag”

PLEASE DO NOT TOUCH ANYTHING ON YOUR LAB TABLES!

Let’s mix it up…

• 4 stations – 20 minutes at each station.• Each station has notes, directions, an activity,

and clean up instructions.• Please be responsible with the materials.• Expectations:– Work together– Low volume– Complete the activity– Stay in your assigned group

Gallery Walkers• Because Ms. K will be working with 1 group of

students while you are doing your gallery walk, it is IMPERATIVE that you follow these rules & directions.

• You will have exactly 1 song per station.• Do NOT move until the music changes.• Do NOT move before the music changes.

YOU MUST BE ON TASK, QUIET, AND AT YOUR ASSIGNED STATIONS AT ALL TIMES OR MS. K

WILL ASK YOU TO SIT DOWN.

-Organize on your plate a HELIUM (He) atom!

-Draw what your plate lookslike

HHelium

4.00260

• Now change your Helium atom into an ION with a charge of -1 on your plate!

• Draw it! 2

HHelium

4.00260

• Draw a Beryllium (Be) atom!

4

BeBeryllium

9.01218

• Make your Beryllium atom into an Ion with a charge of +2

9.01218

• Draw a Lithium atom.

• Make the Lithium atom into an Ion with a charge of -3.

ALKALI METALS

Group 1• Hydrogen is not a member, it

is a non-metal• 1 electron in the outer shell• Soft and silvery metals• Very reactive, esp. with water• Conduct electricity

ALKALINE EARTH METALSGroup 2• 2 electrons in the

outer shell• White colored and

malleable• Reactive, but less

than Alkali metals• Conduct electricity

TRANSITION METALSGroups in the middle

• Good conductors of heat and electricity.

• Some are used for jewelry.

• The transition metals are able to put up to 32 electrons in their second to last shell.

• Can bond with many elements in a variety of shapes.

HalogensGroup 17• 7 electrons in the

outer shell• All are non-metals• Very reactive are

often bonded with elements from Group 1

Noble GasesGroup 18Exist as gasesNon-metals8 electrons in the

outer shell = FullHelium (He) has only

2 electrons in the outer shell = Full

Not reactive with other elements

Let’s Practice!

• You and your partner are responsible for:–Using your new colored periodic table as a

reference.–Answering ALL investigation questions.–Raising your hands when you have questions.–COLLABORATING SUCCESSFULLY to complete

work during the given time

–Value- 50 point in class assignment.

Use your knowledge & periodic table to help you identify the following elements. Also include what

FAMILY they belong to (complete in your notebook):

• HOT Q1: Why is it important to have a system of organization for all of the elements on earth?

• HOT Q2: Why do only electrically stable elements live on the Periodic Table?

• HOT Q3: What are the 2 most reactive groups? Why are they so reactive?HOT Q4: Why don’t the noble gases react?
