• Tuesday, January 22, 2013
• Today we will…
• 8.5(B) identify that protons determine an element's identity and valence electrons determine its chemical properties, including reactivity
• Objective:
• Students will review structures of atoms and valence electrons.
• Tuesday, January 22, 2013

## Above groups 1, 2, 13, 14, 15, 16, 17, 18, list the number of valence electrons in GREEN.

• Periodic Table
• Tuesday, January 22, 2013
• Above groups 1, 2, 13, 14, 15, 16, 17, 18, list the number of valence electrons in GREEN.
• Next to periods 1-3 draw the number of ENERGY LEVELS.
• Make a key at the bottom of your periodic table (teacher demonstrate)

## NITROGEN FAMILY

• Group 5
• 5 electrons in the outer shell
• Can 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-metals
• Reactive

## Fold your periodic table so group 1 lines up with group 17.

• 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
• 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:
• Students will identify and describe the physical properties: luster, malleability, magnetic, conductivity, and density.
• 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
• Physical Properties Lab
• Go to 4 stations and observe the physical properties: luster, malleability, magnetic, and conductivity of 5 different elements.
• Record observations in data table.
• Answer questions at each station.
• Wed./Thurs, January 23 &25, 2013
• 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
• Wed./Thurs, January 23 &25, 2013
• With your table, calculate the density of each element.
• Remember: Density=
• Wed./Thurs, January 23 &25, 2013
• Mass
• Volume
• Calculating the density
• Using the triple-beam balance, measure the mass of each sample.
• Record the mass.
• To measure the volume, fill up the graduated cylinder with 20 mL of water.
• CAREFULLY, drop the element in the water.
• Subtract 20 mL from the new number on the graduated cylinder.
• Record this number as the volume.
• Wed./Thurs, January 23 &25, 2013
• Calculating the density
• Using your calculator, calculate the density of the element.
• Record the density.

• Wed./Thurs, January 23 &25, 2013
• Density of an Element
• Using your calculator, calculate the density of the element.
• Record the density.
• Read “Physical Properties” by yourself or with a partner.
• Wed./Thurs, January 23 &25, 2013
• Conclusion Questions
• What is the formula for calculating density?
• Did the samples of different elements have the same density? Why or why not?
• Did the samples of the same element have the same mass?
• Did the samples of the same element have the same mass?
• Did the samples of the same element have the same density?
• Why is density considered a physical property?
