METALS, NONMETALS, METALLOIDS, NOBLE GASES

• FOUR SECTION FOLDABLE ADVANCED ORGANIZER

2
PROPERTIES OF METALS

• Most elements are metals
• Metals are located left of the Zig Zag line
• Metals have few electrons in their outer energy
  level
• Metals are solid at room temperature except
  Mercury which is a liquid

3
PROPERTIES OF METALS

• Metals are good conductors of heat and
  electricity
• Metals are malleable which means they can be
  flattened into thin sheets
• Metals are ductile which means they can be drawn
  into thin wires
• Metals are shiny

4
EXAMPLES OF METALS

• Gold
• Silver
• Mercury
• Lead
• Iron
• Nickel
• Copper

5
PROPERTIES OF NONMETALS

• Nonmetals are located right of the Zig Zag line
• Nonmetals have almost a complete set of electrons
  in their outer energy level
• Nonmetals are mostly gases at room temperature

6
PROPERTIES OF NONMETALS

• Nonmetals are not good conductors of heat
  electricity
• Nonmetals are not malleable
• Nonmetals are not ductile they are brittle and
  will break or shatter when hit with a hammer
• Nonmetals are not shiny

7
EXAMPLES OF NONMETALS

• Oxygen
• Nitrogen
• Sulfur
• Carbon
• Chlorine
• Fluorine
• Iodine

8
PROPERTIES OF METALLOIDS

• Metalloids are also called semiconductors
• Metalloids border the Zig Zag line
• Metalloids have a ½ complete set of electrons in
  their outer energy level
• Metalloids have some properties of metals and
  some properties of nonmetals.

9
EXAMPLES OF METALLOIDS

• Tellurium-shiny but brittle
• Silicon-semiconductor
• Boron-hard but brittle and a good conductor of
  electricity

10
PROPERTIES OF NOBLE GASES

• Noble Gases are Family 18
• Noble Gases have a complete set of electrons in
  their outer energy level all but Helium have 8.
  Helium has 2.
• Noble Gases are gases at room temperature
• Noble Gases are nonmetals

11
PROPERTIES OF NOBLE GASES

• Noble Gases are colorless
• Noble Gases are odorless
• Noble Gases are unreactive
• Noble Gases are found in very small amounts on
  Earth

12
EXAMPLES OF NOBLE GASES

• Helium
• Argon
• Krypton
• Xenon
• Radon (Radioactive gas)

13
More Vocabulary

• Period a horizontal row of elements on the
  periodic table
• Lanthanides transition metals that follow
  lanthanum (first row at the bottom). They are
  shiny, reactive metals. Some are used to make
  steel.

14
More Vocabulary

• Actinides - transition metals that follow
  actinium (second row at the bottom). They are
  all radioactive and unstable. They can change
  into different elements. Elements after
  plutonium do not occur in nature.

15
More Vocabulary

• Family also called a group, are the columns on
  the periodic table. Most of these elements in a
  family share similar properties
• Metal elements that are shiny and are good
  conductors of thermal energy and electric
  current most metals are malleable and ductile

16
More Vocabulary

• Nonmetal elements that are dull and are poor
  conductors of thermal energy and electric current
• Metalloid elements that have properties of both
  metals and nonmetals sometimes referred to as
  semiconductors.

17
Additional Notes

• The number at the top of the block on the
  Periodic Table is the ATOMIC NUMBER.
• The ATOMIC NUMBER tells you how many PROTONS are
  in the nucleus of the atom.
• The ATOMIC NUMBER is unique to each element.
