Periodic Table Tuesday, January 22, 2013
1. Above groups 1, 2, 13, 14, 15, 16, 17, 18, list the number of valence electrons in GREEN.
2. Next to periods 1-3 draw the number of ENERGY LEVELS.
3. Make a key at the bottom of your periodic table (teacher demonstrate)
ALKALI METALS- Orange
ALKALINE EARTH METALS- Green
TRANSITION METALS- Blue
BORON FAMILY- Red
CARBON FAMILY- Yellow
NITROGEN FAMILY Group 5
5 electrons in the outer shellCan share
electrons to form compounds
Contains metals, metalloids, and non-metals
OXYGEN FAMILY Group 6
6 electrons in the outer shell
Contains metals, metalloids, and non-metalsReactive
Halogens- Purple
Noble Gases- Pink
Rare Earth Metals- Light Blue

Reactivity Tuesday, January 22, 2013
• Fold your periodic table so group 1 lines up with group 17.
• How many valence electrons are in group 1? How many are in group 17?
• Add those together. Do they have a full shell when they combine?
• Compare group 2 with group 16, do you get the same results?

Wed./Thurs, January 23 &25, 2013
8th Grade Science
Today we will…
8.5 (C) interpret the arrangement of the Periodic Table, including groups and periods, to explain how properties are used to classify elements;
Objectives: 1.Students will identify and describe the physical properties: luster, malleability, magnetic, conductivity, and density. 2.They will be able to identify the different families on the periodic table and that the elements in the family share physical properties.
Wed./Thurs, January 23 &25, 2013
8th Grade Science
Physical Properties Lab
1. Go to 4 stations and observe the physical properties: luster, malleability, magnetic, and conductivity of 5 different elements.
2. Record observations in data table.
3. Answer questions at each station.
Wed./Thurs, January 23 &25, 2013
8th Grade Science
Definitions
• Luster – the way an object or substance reflects light. Ex: glitters, sparkles, glossy, glassy, waxy, dull, metallic.
• Conductivity – The ability to transfer heat or electricity through direct contact.
• Malleability – The ability to be hammered into a thin sheet. Ex: silver is very malleable which makes it a good material for jewelry making

Calculating the density
With your table, calculate the density of each element.
Remember: Density=
Wed./Thurs, January 23 &25, 2013
MassVolume
8th Grade Science
Calculating the density
1. Using the triple-beam balance, measure the mass of each sample.
2. Record the mass. 3. To measure the volume, fill up the
graduated cylinder with 20 mL of water.
4. CAREFULLY, drop the element in the water.
5. Subtract 20 mL from the new number on the graduated cylinder.
6. Record this number as the volume.

Density of an Element
1. Using your calculator, calculate the density of the element.
2. Record the density.3. Read “Physical Properties” by yourself or
with a partner.
Wed./Thurs, January 23 &25, 2013
8th Grade Science
Conclusion Questions
COPY and ANSWER the following questions about density on page of your INB.1.What is the formula for calculating density?2.Did the samples of different elements have the same density? Why or why not?3.Did the samples of the same element have the same mass?4.Did the samples of the same element have the same mass?5.Did the samples of the same element have the same density?6.Why is density considered a physical property?

What isn’t chemistry?Why should I care about physical and chemical changes in my everyday life?Where does matter come from and where does it go to if it can’t be created or destroyed?How would scientists predict the properties of a new element & where would it fit on the Periodic Table?What do I have in common with pencil graphite and diamonds?What would the biosphere be like without the 8 common elements in contains?
understanding that all matter in the universe is made up of elements
