Tour of the the Periodic Table

8th Grade Earth and Space Science

Mrs. Liberatore

i am dmitri mendeleev
I am Dmitri Mendeleev!

I made the PERIODIC TABLE !

what is the periodic table
What is the PERIODIC TABLE?
  • Shows all known elements in the universe.
  • Organizes the elements by chemical properties.
the metals non metals and metalloids are organized in certain places on the periodic table
The metals, non-metals, and metalloids are organized in certainplaces on the Periodic Table.
  • Color the nonmetals yellow
  • Color the metalloids blue
  • Color the metals green
what makes an element a nonmetal
What makes an element a nonmetal?
  • Poor conductors of heat and electricity
  • Dull and brittle
  • Less dense than metals
  • Lower melting points and boiling points than metals
what makes an element a metal
What makes an element a metal?
  • Good conductor of heat and electricity
  • Shiny, malleable
  • More dense than nonmetals
  • High boiling points and melting points
what makes an element a metalloid
What makes an element a metalloid?
  • Their properties are in between that of a metal and nonmetal
    • Semi-conductors
    • Some look like metals; some do not
the columns are groups or families
The Columns are Groups or Families
  • Elements with similar chemical properties
  • Some groups have special names
  • Let’s meet them!
the alkali metals group 1
The Alkali MetalsGroup 1
  • Very reactive
  • Cause explosions when mixed with water
  • Metals
  • Shiny
  • Light weight
the alkaline earth metals group 2
The Alkaline Earth MetalsGroup 2
  • Reactive, but not quite as much as Group 1
  • Metals
  • Shiny
  • Light weight
the alkaline chalcogens group 16
The Alkaline ChalcogensGroup 16
  • A.k.a. – the oxygen family
  • Mix of metals and metalloids
  • Many are found in minerals
the halogens group 17
The HalogensGroup 17
  • Often bond with metals from Group 1
  • Very reactive
  • Often form salts
the inert noble gases group 18
The Inert (Noble) GasesGroup 18
  • Rarely react
  • As you move down the column, the gases become more rare
