Periodic Table 2

Periodic Table 2DO NOWName two elements that would have similar properties to Nitrogen. Why is this?

TODAY I WILL LEARN HOW TOIdentify properties of metals, nonmetal and metalloids. Describe how the properties of elements change across a period.Explain how the properties of the first 20 elements of the Periodic Table are related to their atomic structure.

UNIT 4 INCENTIVESThe class who has the highest percentage of homework handed in COMPLETED AND ON TIME (three homeworks this unit) will win a PIZZA PARTY for lunch with my mom and sister.

Properties of:KEY CLOTHCategorizing?If we had to put the key and the cloth into two distinct categories, what would they be?

What are examples of metals and nonmetals? Use the periodic table to help you.

What do you think metalloids are?Properties of MetalsLuster: shinyGood conductors of heat and electricityHigh densityHigh melting pointDuctile: can be drawn out into thin wiresMalleable: can be hammered into thin sheets

Properties of Non-metalsNo luster (dull appearance)Poor conductor of heat and electricityBrittle: breaks easilyNot ductileNot malleableLow densityLow melting pointProperties of MetalloidsSolidsCan be shiny or dullDuctileMalleableConduct heat and electricity better than nonmetals but not as well as metals

Examples ofMetals-

Non-metals-

Metalloids-Valance ElectronsValance electrons: electrons in the outermost shell that determines properties and ways it interactsValance electrons in the first columnElements in the same column have the same number of valance electrons

Same valance electrons = same properties
