2. The Periodic Table Of Elements
Originally constructed and published by Dmitri Mendeleev in 1869.
Families of elements within the Periodic Table of Elements
How the Periodic Table is constructed
Chemical Bonds

3. Dmitri Mendeleev
First to arrange the 63 known elements by atomic mass into a table
Left gaps in the table for new, undiscovered elements
Predicted the properties of unknown elements

4. Families Of Elements
Halogens- highly active elements that have the worst odor and most brilliant color
Alkali Metals- soft, very active with very low melting points
Inert Gases- in contrast with active halogens and alkali metals, inert gases are so inactive that they form only a handful of compounds

5. The Periodic Table Includes…
Atomic Mass- the average mass of an element in atomic mass units
Atomic Number- the number of protons in an atom defines what element it is
Atomic symbol- the atomic symbol is one or two letters chosen to represent an element
Group- vertical columns
Period- horizontal row

7. Chemical Bonds
Covalent Bond- when one or more pairs of electrons are shared by two atoms
Ionic Bond- when one or more electrons from one atom shift to another atom; resulting ions attract each other
No Bond- when atoms do not interact to produce an attractive force

8. No Bond
