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 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.
By number of elctrons,protons in them and their reaction rate
The elements are lined up in order of increasing atomic number (number of protons).
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.
They are in the same column.
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.
You can tell by the location, and the fact that they are both in the same column. Elements in the same column (or group) have similar properties.
The periodic table tells you chemical elements. :)

Valance level
Knowing the column in which an element appears on the periodic table can tell you about its group/family. Elements in the same column typically share similar chemical properties and reactivity due to having the same number of valence electrons.

Atomic weight
where tell me then
it tells us that their chemical properties are similar, and in many cases follow a trend.
The rows on the Periodic table are called "periods" and the increasing atomic number across a period represents additions to the electron orbitals, which cause the properties manifested by individual elements (elements of the same group, or column, have similar properties).
