The Periodic Table of Elements
Block 6 & 7SNC1D1 Grade 9 Science
![Page 2: The Periodic Table of Elements Block 6 & 7 SNC1D1 Grade 9 Science](https://reader035.vdocuments.us/reader035/viewer/2022062720/56649f125503460f94c25bd8/html5/thumbnails/2.jpg)
• The periodic table contains information on all the known
elements of the universe• Metals, metalloids, and non-metals• Rows in the periodic table are called
periods• Columns are called groups
Recall from Wednesday

Each group/family has a name
C. Families

Alkali Metals
First column…called “Group 1”
• VERY REACTIVE metals
• Always found combined in nature with another element
• Soft enough to be cut with a butter knife!

Alkaline Earth Metals
Second column…called “Group 2”
• REACTIVE metals , but not as much as Group 1
• Always combine with non-metals in nature
• Some make up important minerals in our diet

Transition Metals
Middle Section…Groups 3-12
• Hard metals that are less reactive
• Metals used in construction and jewellery
• Also used to make paints and other pigments
![Page 16: The Periodic Table of Elements Block 6 & 7 SNC1D1 Grade 9 Science](https://reader035.vdocuments.us/reader035/viewer/2022062720/56649f125503460f94c25bd8/html5/thumbnails/16.jpg)
The Halogens
Column 17…called “Group 7”
• REACTIVE non-metals and volatile (gaseous)
• Always combine with metals in nature
• Used as disinfectants (Cl) & to strengthen teeth (F)
![Page 17: The Periodic Table of Elements Block 6 & 7 SNC1D1 Grade 9 Science](https://reader035.vdocuments.us/reader035/viewer/2022062720/56649f125503460f94c25bd8/html5/thumbnails/17.jpg)
Noble Gases
Column 18…called “Group 8”
• Very UNREACTIVE gases because they have a full outer shell of electrons
• Used in “neon” signs and balloons
![Page 18: The Periodic Table of Elements Block 6 & 7 SNC1D1 Grade 9 Science](https://reader035.vdocuments.us/reader035/viewer/2022062720/56649f125503460f94c25bd8/html5/thumbnails/18.jpg)

Colors Noble Gases produce in lamp tubes:
• Ne (Neon): orange-red
• Hg (Mercury): light blue
• Ar (Argon): pale lavender
• He (Helium): pale peach
• Kr (Krypton): pale silver
• Xe (Xenon): pale, deep blue
