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.
It is the periodic table of elements. There are no alloys in it.
Krypton is the 36 th element in the periodic table. It is a noble gas belonging to 4th period of the periodic table.
Periodic table group elements with same properties together. Hence their properties can be identified.
There are 6 noble gases in periodic table. The common one is helium.
Argon
It is the periodic table of elements. There are no alloys in it.
by checking in the periodic table
Xenon is listed as the 54th element on the periodic table. It is an inert gas but you will find it on the IUPAC Periodic Table as a "Noble Gas". It has an atomic mass of 131.3 grams.
Krypton is the 36 th element in the periodic table. It is a noble gas belonging to 4th period of the periodic table.
This gas is fluorine.
Ar represents Argon, a noble gas, on the periodic table.
gas
Periodic table group elements with same properties together. Hence their properties can be identified.
Xenon is a noble gas. It belongs to group 18 and period 5 on the periodic table.
Neon, number 10 on the Periodic table.
Radon is a noble gas (non-metal) in the periodic table so it appears in the atmosphere as radioactive gas with a quantity of about 0.01%. the standard state of Radon is gas in atmosphere so it is placed in periodic table as gas...the gas exist since billion of years and history of periodic table is thousands of years....
Noble gases are found in group 18 of the periodic table.
