History
•Dimitri Mendeleev was the author of the 1st periodic table. The modern one is based on his findings and theories in Periodic Chemistry.

History
• It is used by chemists to observe the chemical and physical properties, characteristics, patterns and relationships between over 100 elements in just one chart.

View• Families or groups of elements are
set in the columns (From 1 to 18 and the one of La and Ac).
• Periods are set in the rows (From 1 to 7). P F A MI L I E S O R G R O U P S

Atomic number
• Elements are defined by the number of protons in their nucleus. All elements conform a perfect succession of integer numbers, from one to 118. (This is represented by Z). H

• Each Chemical element on the Periodic table is given a unique Atomic Number.

Metals and non metals
Besides the common ideas asociated with these classification (conductivity, shine, etc.) Chemical features (electronegativity, for instance) define this character, and are shown in the PT.

Families or groups: similar chemical behavior
A group or family is a vertical column in the periodic table. Groups are considered the most important method of classifying the elements.
![Page 15: Table Of The Elements](https://reader036.fdocuments.us/reader036/viewer/2022062423/56814cfb550346895dba1601/html5/thumbnails/15.jpg)
Families or groups: similar chemical behavior
In most of the groups, the elements have very similar properties and exhibit a clear trend in properties down the group.

Periods
• The Periods in the Periodic Table are any of the 7 horizontal rows that contain elements arranged in order of increasing atomic number
![Page 18: Table Of The Elements](https://reader036.fdocuments.us/reader036/viewer/2022062423/56814cfb550346895dba1601/html5/thumbnails/18.jpg)
Periods
• The Atomic number increases as you move across a period (row)
• Each period starts with Alkali metal and ends with a Noble gas
• The first element of each period (row) is most reactive and last element is chemically inert

• The 18 Groups in the Periodic Table are any of the vertical columns that contain elements arranged in order of increasing atomic number
• The Atomic number increases as you go down (in the GROUP)
• Elements with similar properties are arranged in the same group
