∙ 11y agoThere are many factors that go into how elements are arranged in the Periodic Table. The main factor is that they increase left to right by atomic number. Elements are also grouped by families (columns) and periods (rows). Elements of the same family have the same number of valence electrons and also will have similar properties. Certain families will thus bind well ith each other while others will not. Though not organized as so, Atomic Mass usually increases with atmic number, but there are some exceptions to this.

∙ 11y agoExcluding the transition elements each vertical column, called a "group" describes how many electrons are in the outer shell. Group 1 = 1 electron group 2 = 2 electrons etc. The groups go up to 8/0 which describes the last shell as being full. This last column on the right contains the oble gases, which are very unreactive because they have a full outer shell.
Each horizontal column down, called a period, describes how many shells around the nucleus each atom has that holds electrons. For instance, Helium has just one shell holding electrons, below it is Lithium, which has 2 shells to hold its 3 electrons. Below that is Sodium, this has 3 shells that hold electrons

It is called the Periodic Table of Elements.
Scientists from all over the world use the periodic table as it is quicker for equations, and its a symbol all of them will know from the Chinese to the Indian, so its an easier way all round.
In the periodic table chemical elements are orderd in periods and groups.

CO3 is not placed in periodic table. Only elements are arranged in periodic table.
A tool to organize the elements
The properties of elements are found to be periodic when arranged according to atomic number. Hence atomic number is considered as base for arranging the elements.

The periodic table organizes the elements by atomic number (number of nuclear protons).

Dmitiri Mendeleev arranged the Periodic Table of elements in order of increasing atomic masses.

Some people have suggested that Dmitri Mendeleev did first organize elements in a periodic table in a dream.
