There are 11: Name: Nitrogen Symbol: N
Type: Non-Metal Atomic weight: 14.0067
Density @ 293 K: 0.0012506 g/cm3 Atomic volume: 17.3 cm3/mol
Discovered: Nitrogen was discovered by Daniel Rutherford in Scotland in 1772. Rutherford removed oxygen and carbon dioxide from air and showed that the residual gas could not support combustion or living organisms. He called his discovery noxious air.
Name: Oxygen Symbol: O
Type: Non-Metal, Chalcogen Atomic weight: 15.9994
Density @ 293 K: 0.001429 g/cm3 Atomic volume: 14.0 cm3/mol
Discovered: Oxygen was discovered in 1774 by J. Priestley in England and independently by C. W. Scheele in Sweden. The word oxygen is derived from the Greek words 'oxys' meaning acid and 'genes' meaning forming.
Name: Fluorine Symbol: F
Group: Halogen Atomic weight: 18.998403
Density @ 293 K: 0.001696 g/cm3 Atomic volume: 17.1 cm3/mol
Group: Halogen Discovered: 1886
Name: Chlorine Symbol: Cl
Type: Halogen Atomic weight: 35.453
Density @ 293 K: 0.003214 g/cm3 Atomic volume: 22.7 cm3/mol
Discovered: Chlorine was produced first in 1774 by Carl Wilhelm Scheele, who observed the greenish-yellow gas released by the reaction of pyrolusite (manganese dioxide) with the substance we now call hydrochloric acid. Scheele mistakenly thought the resulting gas contained oxygen. In 1810, Sir Humphry Davy confirmed this gas was an element, not a compound. He named it chlorine, from the Greek word 'chloros', meaning pale green.
Name: Helium Symbol: He
Group: Noble Gas Atomic weight: 4.00260
Density @ 293 K: 0.0001787 g/cm3 Atomic volume: ?
Group: Noble Gas Discovered: 1895
Name: Neon Symbol: Ne
Type: Noble Gas Atomic weight: 20.179
Density @ 293 K: 0.0009 g/cm3 Atomic volume: 16.7 cm3/mol
Discovered: Neon was discovered in 1898 by William Ramsay and Morris Travers during experiments with liquid air. The name comes from the Greek word 'neon', meaning new.
Name: Argon Symbol: Ar
Type: Noble Gas Atomic weight: 39.948
Density @ 293 K: 0.001784 g/cm3 Atomic volume: 22.4 dm3/mol at 0 oC, 101.325 kPa.
Discovered: 1894 by Lord Rayleigh and Sir William Ramsay who sought to explain why nitrogen from air appeared to be heavier than nitrogen released from compounds. They discovered that air-sourced nitrogen contained another gas that is nearly one-and-a-half times denser than nitrogen. After isolating the new gas, the first of the noble gases to be discovered, the scientists named it argon ("the inactive one") and found it made up almost one percent of air. Rayleigh said, "Argon must not be deemed rare. A large hall may easily contain a greater weight of it than a man can carry."
Name: Krypton Symbol: Kr
Group: Noble Gas Atomic weight: 83.80
Density @ 293 K: 0.003708 g/cm3 Atomic volume: 38.9 cm3/mol
Group: Noble Gas Discovered: 1898
Name: Xenon Symbol: Xe
Group: Noble Gas Atomic weight: 131.30
Density @ 293 K: 0.00588 g/cm3 Atomic volume: 37.3 cm3/mol
Group: Noble Gas Discovered: 1898
Name: Radon Symbol: Rn
Group: Noble Gas Atomic weight: 222
Density @ 293 K: 0.00973 g/cm3 Atomic volume: 50.5 cm3/mol
Group: Noble Gas Discovered: 1900

What else can I help you with?
What element is 2 on the Periodic Table of Elements?
Helium (He) is the element that is number 2 on the Periodic Table of Elements. It has an atomic number of 2 and is a noble gas.
Is natural gas in the pediodric table?
No, natural gas is not specifically listed in the periodic table. Natural gas is a mixture of hydrocarbon gases primarily made up of methane and small amounts of other gases. Gas elements like methane, which is the primary component of natural gas, can be found in the periodic table as individual elements.
Where are elements with full outer shells located on the periodic table?
Elements with full outer shells, the noble gas elements, are located in the column at the extreme right of the periodic table.
How do you identify What is gas on the periodic table?
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.
Are all Group 1 elements on the periodic table solids?
No. Hydrogen, on a regular periodic table, is the first element in group 1, and it is part of the gas family.
What element is 2 on the Periodic Table of Elements?
Helium (He) is the element that is number 2 on the Periodic Table of Elements. It has an atomic number of 2 and is a noble gas.
How are the elements in group 1 on a periodic table stored?
no it is a gas not a salt.
Is natural gas in the pediodric table?
No, natural gas is not specifically listed in the periodic table. Natural gas is a mixture of hydrocarbon gases primarily made up of methane and small amounts of other gases. Gas elements like methane, which is the primary component of natural gas, can be found in the periodic table as individual elements.

What is the special name for the last column on the periodic table?
The noble gas elements.
Which is the most reactive gas on the periodic table?
Fluorine is the most reactive gas on the periodic table. It readily reacts with almost all other elements, including noble gases like helium.
Are most elements in periodic table metals?
No, most elements in the periodic table are not metals. Elements in the periodic table include metals, nonmetals, and metalloids. Metals make up the majority of the elements in the periodic table, but nonmetals and metalloids also play essential roles.
Are all Group 1 elements on the periodic table solids?
No. Hydrogen, on a regular periodic table, is the first element in group 1, and it is part of the gas family.
What do other elements do to acquire a noble gas configuration?
Other elements can acquire a noble gas configuration by either gaining or losing electrons. Elements on the left side of the periodic table, such as alkali metals, tend to lose electrons to achieve a noble gas configuration. Elements on the right side of the periodic table, such as halogens, tend to gain electrons to achieve a noble gas configuration. Elements in the middle of the periodic table may gain or lose electrons to acquire a noble gas configuration, depending on the specific element and its properties.
Which gas is colourless in a periodic table?
Nitrogen is a colorless gas that can be found on the periodic table.
What is the electronegativity of xenon and how does it compare to other elements in the periodic table?
The electronegativity of xenon is 2.6. This value is relatively low compared to other elements in the periodic table, as xenon is a noble gas and tends to have lower electronegativity values compared to other elements.
