The Periodic Table

Dmitri Mendeleev

• A Russian Chemist that put together the first
  Periodic Table.
• Predicted the existence of unknown elements
• Made one errorHe put the elements in order based
  on Atomic mass, not Atomic Number, which was
  later corrected.
• His table revolutionized the field of Chemistry
  forever.

Important Terms

• Atomic Number the number of protons in the
  element
• Atomic Mass the number of protons plus neutrons
  in the element
• Element A substance composed of atoms having an
  identical number of protons in each nucleus.
• Symbol Abbreviation for an element that is
  unique to each element

5
Important Terms (cont.)

• Periodicity The quality, state, or fact of
  being regularly recurrent or having periods, the
  completion of a cycle, a series of events, or a
  single action.
• Groups/Families Columns on the Periodic Table
  elements with similar properties and
  characteristics
• Rows Run left to right and indicate the
  position of electrons in the atoms of elements

6
Groups/Families/Series

• Lanthanide Series
• Actinide Series
• Metalloids
• Other Common Metals
• Other Nonmetals

• Alkali Metals
• Alkaline Earth Metals
• Transition Metals
• Halogens
• Noble Gases

Periodic Squares

• Whole numbers represent the Atomic Number of the
  element and place on the Periodic Table.
• Capital Letter or Capital Letter with lower-case
  letters represent the symbol of the Element.
• Name is usually given on bigger tables.
• Decimal number represents the average atomic mass
  of that element.
• (Based on isotopes)

Uses for the Periodic Table

• Classifying elements and their physical and
  chemical properties
• Provides a great deal of information about the
  elements and their atoms, such as number of
  protons, electrons, and neutrons, and bonding
  capabilities.
• Gives information to use in mathematical
  calculations and conversions.

9
Uses (cont.)

• Industrial uses, such as making alloys, hardening
  glass, making new fuels, and determining the
  chemical composition of certain substances.
• Commercial uses, such as making jewelry, cameras,
  fabrics, fireworks, tools and appliances, and
  neon signs.
