![Page 1: There are more than 100 elements and some have similar properties as shown on the periodic table of elements. Just WHERE are these elements with similar](https://reader035.vdocuments.net/reader035/viewer/2022062719/56649ec75503460f94bd3546/html5/thumbnails/1.jpg)
there are more than 100 elements and some have similar properties as shown on the periodic table of elements.
Just WHERE are these elements with similar properties?
![Page 2: There are more than 100 elements and some have similar properties as shown on the periodic table of elements. Just WHERE are these elements with similar](https://reader035.vdocuments.net/reader035/viewer/2022062719/56649ec75503460f94bd3546/html5/thumbnails/2.jpg)
Where are they located on the Periodic Table of Elements?
Look in your book (p. 604-65) for the zigzag line!

What are the properties of metals, nonmetals, and
metalloids?

Draw a triple Venn diagram to compare their properties

metals ---- nonmetals• Solids at room
temp. (except mercury)
• Most are gases

metals ----- nonmetals
• higher melting points• lower melting points
![Page 7: There are more than 100 elements and some have similar properties as shown on the periodic table of elements. Just WHERE are these elements with similar](https://reader035.vdocuments.net/reader035/viewer/2022062719/56649ec75503460f94bd3546/html5/thumbnails/7.jpg)
metals ---- nonmetals• malleable (can be pounded & shaped)
• harder
• brittle (break easily)
• Softer than metals

metals ---- nonmetals
• Ductile
(can be drawn into wire)
• Not ductile

metals ---- nonmetals
• Good conductors of heat and electricity• Poor conductors
(good insulators)

Metalloids• Have some of the properties of metals and
properties of nonmetals• Include semiconductors (Used in
electronics; can conduct but not as good as metals)

• Steel is an alloy of iron with about 1 percent carbon.
• It may also contain other elements, such as manganese.
• Used to make almost everything from skyscraper girders, automobiles, and appliances to thumb tacks and paper clips
• steel is one of the world's most vital materials.
