Periodic Table of Elements

1
The periodic table of elements

• S c I e n c e 7

2
I am Dmitri Mendeleev!

• I made the PERIODIC TABLE !

3
Periodic table of elements

• A toll that aids in identifying the physical and
  chemical properties of elements.
• Helps you to remember the chemical symbols of
  elements their atomic size, and their metallic
  properties and nonmetallic properties.

4
Periodic table of elements

• Horizontal rows -gt period or series
• Vertical column -gt group or family

5
Periodic table of elements

• Group IA Alkali Metals
• Group IIA Alkaline Earth Metals
• Group IIIA Boron Family
• Group IVA Carbon Family
• Group VA - Nitrogen Family
• Group VIA Oxygen Family
• Group VIIA Halogens Family
• Group VIIIA Noble Gases

7
Periodic table of elements

• Sanderson line ladder-like line that divides
  metals and nonmetals.
• Elements to the left are metals while on the
  right are nonmetals.
• B, Si, Ge, As, Sb, Te, Po and At are called
  metalloids.

Properties of Metals

• Good conductors of heat and electricity
• Lustrous and shiny.
• Ductile (can be stretched into thin wires)
• Malleable (can be pounded into thin sheets)
• High melting point
• Usually solid (except Hg) at room temperature
• A chemical property of metal is its reaction with
  water which results in corrosion.

10
Properties of Non-Metals

• Poor conductors of heat and electricity
• Non-lustrous (dull appearance)
• Not ductile or malleable
• Brittle and break easily
• Many non-metals are gases.
• Maybe solid, liquids or gases at room temperature

Sulfur
11
Properties of Metalloids

• Have properties of both metals and non-metals
• Solids that can be shiny or dull.
• Conduct heat and electricity better than
  non-metals but not as well as metals.
• They are ductile and malleable.

Silicon
12
Region Metals
13
Group1 Alkalai Metals

• 1 valence electron
• Very Reactive

14
Group 2 Alkaline Earth Metals

• 2 valence electrons
• Very reactive, but less than alkali metals

15
Groups 3 12 Transition Metals

• 1-2 valence electrons
• Less reactive than alkaline earth metals because
  they dont give away their electrons as easily
• Bottom 2 row are the Lanthanide Actinide series

16

• Lanthanide Series
• shiny reactive metals
• Most found in nature
• Actinides Series
• radioactive and unstable
• Most are man-made not stable in nature

17
Region Metalloids
18
Region Nonmetals
19
Group 17 Halogens

• 7 valence electrons
• Very reactive
• Nonmetals

20
Group 18 Noble Gases

• 8 valence electrons (except He which only has 2)
• Happy because their outer electron shell is
  filled!
• NON REACTIVE (inert)gases
• Nonmetals

21
