Why is the Periodic Table important to you?
• The periodic table is the most useful tool to a chemistry student.
• You get to use it on your test.
• It organizes lots of information about all the known elements.

Pre-Periodic Table Chemistry …
• …was a mess!!!• No organization of
elements.• Imagine going to a grocery
store with no organization!!• Difficult to find information.

Dmitri Mendeleev: Father of the Table
HOW HIS WORKED…• Put elements in rows
by increasing atomic weight.
• Put elements in columns by the way they reacted.

The Current Periodic Table• The elements are put in rows by increasing
ATOMIC NUMBER!!• The horizontal rows are called periods and are
labeled from 1 to 7.• The vertical columns are called groups are
labeled from 1 to 18.

• Horizontal rows in the periodic table are called periods (LEFT TO RIGHT)
• Vertical columns are called groups
(UP AND DOWN)• The elements are arranged based on their
valence electrons outside the nucleus
Periods and Groups

The truth about groups…
Elements in the same group have similar chemical and physical properties!!

Families on the Periodic Table
• Columns are called groups or families.
• Families have characteristics in common .
• Check out Group 11 (Gold, Silver and Copper)
