It's Is Arranged By Matals, NonMetals,Matalliods And Moble Gases
The groups are arranged according to the number of valence electrons. The elements in the same group has a same number of valence electrons. They have equal chemical properties.
Groups are arranged as vertical columns. They are also called families.
CO3 is not placed in periodic table. Only elements are arranged in periodic table.
