DirectionsUse the periodic table in your journal.Read through the PowerPoint and color as

indicated

Period and Groups

When you look at a periodic table, each of the rows is considered to be a different period

When a column goes from top to bottom, it's called a group. The elements in a group have the same number of electrons in their outer shell. We call them valence electrons.

Families on the Periodic TableElements on the periodic table can be

grouped into families bases 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.

ALKALI METALSGroup 1Hydrogen is not a member, it

is a non-metalThese have only 1 electron in

the outer shellSoft and silvery metalsVery reactive, esp. with waterGood conductors of electricity

Color these light blue and label“Alkali Metals”

ALKALINE EARTH METALSGroup 2These have 2 electrons

in the outer shellWhite and malleableThey are reactive, but

less than Alkali metalsConduct electricity

Color these dark green,and label “Alkaline Earth

Metals”

TRANSITION METALSGroups 3- 12

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.

Color Dark Blue and label

“transition metals”

METALS Metals includeAluminum (Al)Gallium (Ga)Indium(In)Tin (Sn)Thallium (Tl)Lead (Pb)Bismuth (Bi)

Color bright green and label “Metals”

METALLOIDSThese elements are:

Boron (B)Silicon (Si)Germanium (Ge)Arsenic (As)Antimony (Sb)Tellurium (Te)Polonium (Po)

Color these red, and label “Metalloids”

NON-METALSNon-metals include

Carbon (C)Nitrogen (N)Oxygen (O)Phosphorus (P)Sulfur (S)Selenium (Se)Hydrogen (H)

Color Yellow and label “Non-Metals”

HalogensGroup 177 electrons in the

outer shellAll are non-metalsVery reactive are

often bonded with elements from Group 1

Color Purple and label “Halogens”

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

Color a color you have not used and

label“Noble Gases”

Check your work!Check to make sure the pattern on your periodic table

looks like this. The colors DO NOT match, so don’t worry about the colors

*Now, you will watch a BrainPOP video about the periodic table.

*TAKE NOTES! There will be a quiz at the end that you will turn in.

*Click this link:

The username and password are written on the board

*What characteristics do alkali metals and alkaline earth metals have in common? (the same)?

a)They are good conductors of electricity

b)They are shiny and strong

c)When you mix them with water, they form alkaline solutions.

*Carbon has an atomic number of 6. What else does this tell you?

a)It has 6 neutrons

b)It has 6 protons

c)It weighs 6 grams

*What do the red and blue circles in the nucleus represent?

a)Positrons and neutrons

b)Protons and neutrons

c)Protons and electrons

*What information does the period an element is in tell us?

a)All the elements in that period have the same number of protons

b)All the elements in that period have the same number of energy levels (electron shells)

c)All the elements in that period have the same number of electrons

True or False?

Periods are the horizontal rows.

Groups are the vertical columns.

*Molecules are made out of atoms. So, we know that:

a)Molecules must have at least one proton

b)It has 6 protons

c)It weighs 6 grams

*Turn your paper in to the box at the front table.

*Then, take out your periodic table from yesterday and some colors.

When you finish..Take notes on the next clean page in your journal about this information:
