Metals vs. nonmetals
![Page 2: States of matter; solids](https://reader035.fdocuments.net/reader035/viewer/2022062412/5a4d1ad87f8b9ab059973ce5/html5/thumbnails/2.jpg)
Which elements are metals?
Metals are on the left side of the periodic table
![Page 3: States of matter; solids](https://reader035.fdocuments.net/reader035/viewer/2022062412/5a4d1ad87f8b9ab059973ce5/html5/thumbnails/3.jpg)
Properties of METALS
Solids at room temp. except MercuryShiny “metallic” High DensityMalleable DuctileConductor of electricityConductor of heat

Periodic Table
All the elements shaded in yellow have those metallic properties.

Some common uses of metals are
in sprinkler-systems. (Bismuth)in road flares; the red color. (Strontium)in medicine; absorbs harmful x-rays & gamma rays (Barium)

Periodic Table
The elements in Group 1 are the absolute best of all metals! They are called ALKALI METALS

Which elements are NONMETALS?
Nonmetals are on the right side of the periodic table
![Page 8: States of matter; solids](https://reader035.fdocuments.net/reader035/viewer/2022062412/5a4d1ad87f8b9ab059973ce5/html5/thumbnails/8.jpg)
Properties of NONMETALSMostly gases at room
temp. Dull; not shinyLow DensityBrittle; not malleableNon- conductors

Periodic Table
All the elements shaded in blue have those nonmetallic properties.

Some common uses of nonmetals are
in dandruff shampoos (Selenium)in toothpaste (Fluorine)in rayon (Sulfur)

Periodic Table
The elements in Group 17 are the absolute best of all nonmetals!
Group 17 elements are called HALOGENS
(or the worst of all metals!)

What about the green elements?
These are called METALLOIDS.
![Page 13: States of matter; solids](https://reader035.fdocuments.net/reader035/viewer/2022062412/5a4d1ad87f8b9ab059973ce5/html5/thumbnails/13.jpg)
Properties of METALLOIDSThey are the transition elements
between metals and nonmetals
Some are shiny (aluminum)Some are dull (arsenic)
Most are considered semi-conductors

Some common uses of metalloids are
in aerospace (strong but light) (Boron)in infrared detectors (Germanium)in rat poisoning (Arsenic)

Pick one element that interests you; metal or
nonmetal! periodic table
