									The Elements

Hydrogen - Calcium
Hydrogen
    • Hydrogen is the most
      abundant element in
      the universe. It is the
      fuel that burns in stars.
    • It is the simplest
      element.
    • Hydrogen is a gas
      under standard
      conditions.
    • Hydrogen is used for
      rocket fuel and
      explosives.
Helium
     • Helium is a gas under
       standard conditions
       and is found in all
       stars.
     • Helium is the second
       most abundant
       element in the
       universe.
     • Helium is used as a
       lifting gas for balloons
       and airships
Lithium
    • Lithium is a
      lightweight metal.
    • Lithium is used as
      part of an alloy to
      make lightweight
      aircraft.
    • Lithium is also used in
      batteries and
      medicines for
      psychiatric disorders.
Beryllium
     • Beryllium is a metal.
     • It is used as an alloy
       for aircraft, rocket fuel
       and in mineral form
       makes the gems
       Emerald and
       aquamarine.
Boron
   • Boron is a metalloid.
   • Boron is mostly found
     in mineral form as the
     mineral borax.
   • Boron is used to
     harden steel and to
     make rocket parts
     because it resists
     heat.
Carbon
   • Carbon is a nonmetal.
   • Molecules that
     contain carbon make
     up all living cells.
   • Carbon in different
     forms is used as
     charcoal, graphite
     and diamonds.
Nitrogen
    • Nitrogen is a gas.
    • Nitrogen makes up
      the majority of our
      atmosphere.
    • Nitrogen is used to
      make ammonia,
      fertilizers and
      explosives.
Oxygen
   • Oxygen is a gas.
   • Oxygen is the 3rd
     most abundant
     element in the
     universe.
   • We need to breath
     oxygen to live. It is
     also used in welding,
     and making steel.
Fluorine
    • Fluorine is a gas.
    • Fluorine is the most
      reactive element and
      is rarely found alone.
    • Fluorine compounds
      are used in rat
      poisons, etching glass
      and refrigerants.
Neon
  • Neon is a gas.
  • Neon is un-reactive
    and is therefore not a
    part of many
    molecules.
  • Because it glows red
    when a current is
    passed through it, it is
    used in lights.
Sodium
   • Sodium is a metal.
   • Sodium is extremely
     reactive with water.
   • Sodium vapor is used
     as lighting.
   • Sodium compounds
     make up things like
     baking soda, table
     salt.
Magnesium
     • Magnesium is a
       metal.
     • Magnesium is used to
       make lightweight
       alloys and burns with
       a very bright white
       light for fireworks.
Aluminum
    • Aluminum is a metal.
    • Aluminum is used to
      make aluminum foil,
      alloys and wires.
Silicon
    • Silicon is a metalloid.
    • Silicon is used in
      making glass, quartz.
    • Silicon is also used in
      memory chips in
      computers and semi-
      conductors.
Phosphorus

    • Phosphorus is a non-
      metal.
    • Phosphorus is used in
      fireworks, detergents
      (brightens), fertilizers.
Sulfur
   • Sulfur is a non-metal.
   • Sulfur is used in
     gunpowder, paper,
     matches, drugs
     (antibacterial), paint
     etc.
Chlorine
    • Chlorine is a non-
      metal.
    • Chlorine is used as a
      disinfectant (water
      treatment) and
      combines with metals
      to form salts.
Argon
   • Argon is a gas.
   • Argon is very un-
     reactive and does not
     form compounds.
   • Argon is used to fill
     light bulbs (oxygen
     would corrode the
     filament)
Potassium
     • Potassium is a metal.
     • Potassium explodes
       when it comes in
       contact with water.
     • Potassium
       compounds are used
       in fertilizers.
Calcium
    • Calcium is a metal.
    • Calcium is needed to
      make bone/teeth.
    • Calcium compounds
      are used to make
      chalk, cement.
