Non-metals: To the right on the periodic table Properties of non-metals vary a lot more than properties of metals Many are gases at room temperature Bromine is a liquid If it is solid: dull appearance CANNOT be pounded or shaped into a wire Poor conductors of heat Poor conductor of electricity Metals: Most elements are metals (left side of periodic table) Conducts electricity well Conducts heat well Shiny in appearance CAN BE SHAPED (pounded, bent or drawn into wire) Solids at room temp (except mercury-liquid) Metalloids: Have properties of both METALS and NON METALS On either side of zigzag line on periodic table Silicon is the most common-(2nd most common in Earth’s crust) Used in semiconductors – sometimes conducts electricity Non-metals: To the ___________ on the periodic table ____________of non-metals vary a lot more than properties of metals Many are __________ at room temperature Bromine is a ___________ If it is solid: __________ appearance __________ be pounded or shaped into a wire Poor ___________ of heat Poor conductor of ____________ Metals: Most elements are metals (________ side of periodic table) Conducts ___________ well Conducts __________ well _____________ in appearance CAN BE ____________ (pounded, bent or drawn into wire) _________ at room temp (except mercury-liquid) Metalloids: Have properties of both __________ and _____________ On either side of ____________ line on periodic table _________ is the most common-(2nd most common in Earth’s crust) Used in ____________ – sometimes conducts electricity
