They are also ductile, which allows them to be drawn into wires. They do not break easily when hammered, but are flattened into sheets. This property is known as malleable. Because  electricity and heat pass easily through them, metals are also known as conductors.]]> 2018-04-26 18:07:53 UTC https://padlet.com/ortiztan000/c5yi33wt859p/wish/255776319 ortiztan000 https://padlet.com/ortiztan000/c5yi33wt859p/wish/255781894 Ruthenium is a metal because it has a high luster. It is also malleable.  ]]> 2018-04-26 18:19:48 UTC https://padlet.com/ortiztan000/c5yi33wt859p/wish/255781894 ortiztan000 https://padlet.com/ortiztan000/c5yi33wt859p/wish/255782785 Non-metals are sort of the opposite of metals. They are brittle, which means they break easily when hammered. They are also dull, which means they aren't shiny, no luster. They are also poor conductors. ]]> 2018-04-26 18:21:28 UTC https://padlet.com/ortiztan000/c5yi33wt859p/wish/255782785 ortiztan000 https://padlet.com/ortiztan000/c5yi33wt859p/wish/255786165 Carbon is a non-metal because it it is dull and brittle. ]]> 2018-04-26 18:27:37 UTC https://padlet.com/ortiztan000/c5yi33wt859p/wish/255786165 ortiztan000 https://padlet.com/ortiztan000/c5yi33wt859p/wish/255852895 Metaloids have some properties of both non-metals and metals. Some may be malleable, but they are dull. The main thing about metaloids though is that they are semi-conductors, meaning they control when they conduct  heat and electricity. ]]> 2018-04-26 23:00:52 UTC https://padlet.com/ortiztan000/c5yi33wt859p/wish/255852895 ortiztan000 https://padlet.com/ortiztan000/c5yi33wt859p/wish/255853367 Silicon is a metaloid because it is a semiconductor, even though it has high luster and is malleable. That is why it is used in electronic devices, such as computers.]]> 2018-04-26 23:05:44 UTC https://padlet.com/ortiztan000/c5yi33wt859p/wish/255853367 ortiztan000 https://padlet.com/ortiztan000/c5yi33wt859p/wish/255853818 Tantalum is classified as metal because it has high luster, and is malleable and ductile. It is a silvery, shiny gray color, and is super hard. Its size depends on what it's used for. Tantalum is useful because it helps make alloys( a mixture of an element and metal sometimes used in the silver rims of car wheels ). It is also used to make water tanks and bridges. ]]> 2018-04-26 23:10:24 UTC https://padlet.com/ortiztan000/c5yi33wt859p/wish/255853818 ortiztan000 https://padlet.com/ortiztan000/c5yi33wt859p/wish/255859558 Phosphorus is considered a non-metal because it is brittle and can be a dull color depending on where it is found. Phosphorus is a mineral that can be found in the human body. Phosphate minerals contain phosphorus. It is mainly red and white. Phosphorus is useful because it is on the side of matchboxes, where they light up. It is also used in fertilizers and helps make steel.  ]]> 2018-04-27 00:03:35 UTC https://padlet.com/ortiztan000/c5yi33wt859p/wish/255859558 ortiztan000 https://padlet.com/ortiztan000/c5yi33wt859p/wish/255861655 2018-04-27 00:20:08 UTC https://padlet.com/ortiztan000/c5yi33wt859p/wish/255861655 ortiztan000 https://padlet.com/ortiztan000/c5yi33wt859p/wish/255861900 Antimony is a metalloid because it is brittle, but is silvery gray s and lustrous. It is hard and rough. It is big depending on its size. Although it is poor in conduction itself, it is used to make semiconductor items, such as infrared detectors( which react to infrared radiation) and diodes. Diodes are currents that flow only in one direction. Those are some ways phosphorus is useful. ]]> 2018-04-27 00:22:19 UTC https://padlet.com/ortiztan000/c5yi33wt859p/wish/255861900
