What is Periodic Table????

  • The Periodic Table is a tabular arrangement of the chemical elements , ordered by their atomic number (number of protons in the nucleus),electron configurations and recurring chemical properties.
  • The rows of the table are called periods and the columns are called groups.

Why Is the Periodic Table Important?

  • The Periodic Table is important because it is organized to provide a lot of information about elements and how they relate to each other in one easy-to-use reference:
  • The table can be used to predict properties of elements, even those that have not been discovered.
  • Columns (groups) and rows (periods) indicate elements that share similar characteristics.
  • Columns (groups) and rows (periods) indicate elements that share similar characteristics.
  • The table provides important information used to balance chemical equations.

How to use a Periodic Table??

The periodic table contains informative cells for each element arranged by increasing atomic number and chemical properties.Each element's cell typically contains:
  • The element's symbol. Symbols are the abbreviations of the element's name. In some cases, the abbreviation comes from the element's Latin name.
  • The element's symbol. Symbols are the abbreviations of the element's name. In some cases, the abbreviation comes from the element's Latin name.
  • The element's name. Many periodic tables will include the name to help those who may not remember all the symbols for elements.
Many periodic tables identify element types using different colors for different element types. These include the alkali matals , alkaline earths ,basic metals , semi metals, transition metals, non metals , lanthanides , actinides , halogens and nobel gases.
