Periodic Table

Ptable or the periodic table is an application that includes The periodic table of chemical elements. You find a chemical elements list, when you click on one chemical element you get information about this chemical element. Periodic table elements are presented in increasing atomic number. The science table includes chemical elements with similar properties like halogens and the noble gases.

This the periodic table show you the chemistry periodic table. you can access to periodic table elements just by giving the name of the chemical element or just his abreviation.

The periodic table includes :

• Noble gases

• The post-transitional metals

• Lanthanoids

• Semimetals

• Actinoids

• Shchelochnozemelny metals

• Other nonmetals

• Alkali metals

• Halogens

• The transitional metals

-The chemical elements abre sorted by 10 categories:

• Lanthanoids

• Semimetals

• The transitional metals

• Noble gases

• Shchelochnozemelny metals

• The post-transitional metals

• Halogens

• Actinoids

• Alkali metals

• Other nonmetals

For every periodic table elements you will find these information (Hydrogen as example )
