What is the description of noble gas?
: any of a group of rare gases that include helium, neon, argon, krypton, xenon, and usually radon and that exhibit great stability and extremely low reaction rates. — called also inert gas.
What are 3 chemical properties of noble gases?
The Chemical Properties Noble gases are odorless, colorless, nonflammable, and monotonic gases that have low chemical reactivity. The full valence electron shells of these atoms make noble gases extremely stable and unlikely to form chemical bonds because they have little tendency to gain or lose electrons.
Why it is called noble gas?
The noble gases, in order of their density, are helium, neon, argon, krypton, xenon and radon. They are called noble gases because they are so majestic that, in general, they don’t react with anything. For this reason they are also known as inert gases.
Which is the most flammable gas?
1) Chlorine Trifluoride is the most flammable gas Of all the dangerous chemical gases, chlorine trifluoride is known to be the most flammable.
What is the other name of noble gases?
Group 8A — The Noble or Inert Gases. Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds.
What are the physical properties of noble gases?
Properties of noble gases: Noble gases are colourless, odourless, tasteless, nonflammable gases. All the Noble gases have eight electrons in their outermost electron shell. Noble gases have similar chemical and physical properties because they all have eight electrons in their outer shell.
Which compounds have noble gases?
Many types of noble gas compounds are theoretically possible. This list includes compounds which have been observed: noble gas halides (e.g., xenon hexafluoride – XeF 6, krypton fluoride – KrF2) noble gas clathrates and clathrate hydrates (e.g., Ar, Kr, and Xe clathrates with β-quinol, 133Xe clathrate)
What are the noble gases?
Noble gas. The noble gases make a group of chemical elements with similar properties: under standard conditions, they are all odorless, colorless, monatomic gases with very low chemical reactivity. The six noble gases that occur naturally are helium, neon, argon, krypton, xenon, and the radioactive radon.
What are the noble gases on the periodic table?
The noble gases are group 18 on the periodic table, which is the column of elements on the right side of the table. There are seven noble gas elements: helium, neon, argon, krypton, xenon, radon, and oganesson.
