The Periodic Table of Elements
![Page 2: The Periodic Table of Elements. Elements Elements are a PURE substance that cannot be broken into simpler substances. The elements, alone or in combinations](https://reader036.vdocuments.net/reader036/viewer/2022062516/56649e565503460f94b4dc5d/html5/thumbnails/2.jpg)
ElementsElements are a PUREsubstance that cannot bebroken into simplersubstances. The elements, alone or incombinations (COMPOUNDS),make up our bodies, ourworld, our sun, and in fact, theentire universe.

Properties of Metals
Conductors Metals are
good conductors of electricity and heat

Properties of Metals
A chemical property of metal is its reaction with water and oxygen. This results in corrosion and rust.

Nonmetals
![Page 13: The Periodic Table of Elements. Elements Elements are a PURE substance that cannot be broken into simpler substances. The elements, alone or in combinations](https://reader036.vdocuments.net/reader036/viewer/2022062516/56649e565503460f94b4dc5d/html5/thumbnails/13.jpg)
Properties of Nonmetals
Nonmetals occur to the right of the dark zig-zag on the periodic table. Although Hydrogen is on the left, it is also a nonmetal because of its physical and chemical properties .

Properties of Nonmetals
Nonmetals do not have luster; they are dull.

Properties of Nonmetals
BrittleNonmetals are
brittle so they break easily. This means nonmetals ARE NOT ductile or malleable.
![Page 16: The Periodic Table of Elements. Elements Elements are a PURE substance that cannot be broken into simpler substances. The elements, alone or in combinations](https://reader036.vdocuments.net/reader036/viewer/2022062516/56649e565503460f94b4dc5d/html5/thumbnails/16.jpg)
Properties of Nonmetals
Many nonmetals are gases at room temperature.

Properties of Nonmetals
They also have a low melting point. This is why they are poor conductors of heat and electricity.
