Oxygen, helium, hydrogen, carbon dioxide and methane are five different gases.
The element in group 18 period 5 is xenon. Xenon is a noble gas known for its inert properties and is commonly used in various lighting and imaging applications.
It is a Noble(Inert) Gas and found in the extreme right hand column of the Periodic Table, under the symbol 'Xe'.
Xenon is in Group 18, the "inert" elements.
The reason why nitrogen isn't inert is due to the layout of electrons around the nucleus. the electrons are found in layers/shells. For all elements except the noble gases the outer most shell is incomplete. Having a complete outer shell is the most stable any atom will get as it requires massive quantities of energy to remove them. The noble gases have full outer shells and this is why they are inert. All the other elements try to achieve this state. I will use nitrogen as an example. Nitrogen has 5 electrons in its outer most shell. The closest noble gas is Neon with 8 electrons in its outer shell. For nitrogen to achieve a full outer shell it needs 3 more electrons which it will find through bonding to other elements. Basically put nitrogen isn't inert because it will react with other elements to try and achieve a full outer shell of 8 electrons.
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.
inert or noble
Still, inert, fixed.
inert
The element with 54 electrons is Xenon (Xe). Xenon is an Inert Gas in Period 5 of the Periodic Table. Xenon has 54 electrons in 5 shells with 8 electrons in the outer shell.
== == 95% Argon 5% CO2 is most commonly used for spray MIG.
The next heavier noble gas after radon is ununseptium, with an atomic number of 117.
Doublecheck the O, INERT is the closest I could find. See the related link for more information.
