An element is classified as a metal if it is malleable, ductile, has luster, and is a conductor.

An element is considered a nonmetal if it is brittle, dull, or is a poor conductor or heat and electricity.

Metalloids can have characteristics of both nonmetals and metals. Metalloids can also be semiconductors. ]]> 2018-04-27 14:12:38 UTC https://padlet.com/truonvin001/43m2umxd4kdi/wish/256021733 truonvin001 https://padlet.com/truonvin001/43m2umxd4kdi/wish/256024515 Aluminum is classified as a metal on the periodic table because it is malleable, is a good conductor, and has luster. Aluminum is used in a wide variety of everyday items such as foil, planes, cars, and utensils.]]> 2018-04-27 14:19:06 UTC https://padlet.com/truonvin001/43m2umxd4kdi/wish/256024515 truonvin001 https://padlet.com/truonvin001/43m2umxd4kdi/wish/256027163 Helium is classified as a nonmetal because it has no luster, and is not malleable. Helium is used in balloons, satellites, and supermarket checkouts.]]> 2018-04-27 14:24:44 UTC https://padlet.com/truonvin001/43m2umxd4kdi/wish/256027163 truonvin001 https://padlet.com/truonvin001/43m2umxd4kdi/wish/256028681 Boron is a metalloid because it is a semiconductor, has luster, it is brittle, and it is ductile. Boron is used in rocket fuel igniters.]]> 2018-04-27 14:27:36 UTC https://padlet.com/truonvin001/43m2umxd4kdi/wish/256028681
