The elements are lined up in order of increasing atomic number (number of protons).
By number of elctrons,protons in them and their reaction rate
The periodic table shows the atomic number, symbol, mass number, density of an element. Elements are arranged in periodic table such that their physical and chemical properties follows varies in a systematic way.
Periods in the periodic table tell you the number of electron shells an element has. As you move across a period from left to right, the number of protons, electrons, and valence electrons increases by one, resulting in elements with similar chemical properties being grouped together.
The periodic table itself will not tell you if an element is a gas or not. All elements have a melting point and a boiling point. For this information you need to look at a table of the PROPERTIES of the elements. However, all the elements in column 18 and many of the elements towards the top of column 17 and to some extent 16 are gasses at room temperature, as are all the elements in row 1.

The periodic table tells you chemical elements. :)

where tell me then
The periodic table is in order of atomic mass
The atomic number of each element is on the periodic table. The elements are arranged on the periodic table in order of increasing atomic number.
They are in the same column.
By number of elctrons,protons in them and their reaction rate
Elements in the same period has same number of valence shells.There are 7 periods in Periodic Table.
The periodic table tells you that elements in the same group have similar chemical properties because they have the same number of valence electrons. This influences how they react with other elements and helps predict their behavior in compounds.
Elements with similar properties are found in the same group or column on the periodic table. This is because they have the same number of valence electrons, which influences their chemical behavior. Elements in the same group tend to react in similar ways and have comparable physical properties.
