-Metals are luster, meaning they are shiny
-Most metals are ductile, meaning they can be turned into wires
-Most metals are malleable, so they can be hammered into thin sheets]]> 2018-04-27 14:13:20 UTC https://padlet.com/georgjon002/t5ezumfaf5wx/wish/256022089 georgjon002 https://padlet.com/georgjon002/t5ezumfaf5wx/wish/256023281 -Nonmetals are not malleable or ductile
-Solid nonmetals are brittle and can break easily
-Nonmetals are also dull, meaning not shiny
-Nonmetals are insulators because they are not good conductors.]]> 2018-04-27 14:16:14 UTC https://padlet.com/georgjon002/t5ezumfaf5wx/wish/256023281 georgjon002 https://padlet.com/georgjon002/t5ezumfaf5wx/wish/256024115 -Metalloids have properties of metals and nonmetals
-Metalloids are called semiconductors since they work as conductors in some conditions
-Since metalloids are semiconductors, they are useful in electronics.]]> 2018-04-27 14:18:09 UTC https://padlet.com/georgjon002/t5ezumfaf5wx/wish/256024115 georgjon002 https://padlet.com/georgjon002/t5ezumfaf5wx/wish/256026225 1) Aluminum is classified as a metal because it has luster, it has a very high melting point, is ductile, and can be smashed into sheets.
3) Aluminum is used to make many utensils, cans, because it can be easily formed.]]> 2018-04-27 14:22:45 UTC https://padlet.com/georgjon002/t5ezumfaf5wx/wish/256026225 georgjon002 https://padlet.com/georgjon002/t5ezumfaf5wx/wish/256249391 1) Krypton is classified as a nonmetal because it is a gas with no color, so it is dull and it has a low melting point.
3) Krypton is used as a filling gas for energy-saved flourescent ligths.

3) Boron is used as a rocket fuel igniter.
