Na or Sodium (at no 11, at wt 22.997) is a Metal, NOT a Gas. Further it is one of the Most Chemically Active elements in the whole Periodic Table.
If you are interested in Chemistry, I'd suggest that you get a copy of "Wonderful Life with the Elements" by Bunpei Yorifuji. (available from Amazon for about $12) I just wish that it had been around when I was first starting.
On first glance, it looks like a kid's picture book, but it really contains some first rate stuff, very well presented.
Neon is a Noble Gas.
Radon is not the most inert gas in the atmosphere. Radon is a radioactive gas and is chemically inert, but it is relatively rare in the atmosphere compared to the noble gases like helium, neon, argon, krypton, and xenon, which are considered the most inert due to their stable electron configurations.
helium
'Royal gas' is not a term used in chemistry. Perhaps you mean "noble gas", if so yes "inert gas" and "noble gas" often mean the same thing. However, oxides and fluorides of some of the "noble gasses " do exist, it might be best to think of them as "noble" rather than "inert". Xe, forms oxides.
Helium has two natural isotopes and is an inert noble gas.
Helium (He) is a noble (inert) gas placed in the group 18 of the Periodic Table.Helium falls in inert gas. It is stable and non-reactive.
Neon is an inert noble gas.
No, radon is an inert noble gas.
Noble gas or inert gas.
Neon is a Noble Gas.
Radon is not the most inert gas in the atmosphere. Radon is a radioactive gas and is chemically inert, but it is relatively rare in the atmosphere compared to the noble gases like helium, neon, argon, krypton, and xenon, which are considered the most inert due to their stable electron configurations.
Inert means they don't react. Group 18, the noble gases, are inert.
inert or noble
Radon is an inert or "noble" gas.
Helium is a Noble Gas. It belongs to the group 18 (VIIIa) of the periodic table.
Noble gases have a stable electron configuration. So they are less reactive.
Inert gas = Noble gas Helium, Neon, Argon, Krypton, Xenon, Radon
