What are some other names for Noble gases?
Another name for noble gases is inert gases.
What are the differences between atmospheric nitrogen and laboratory nitrogen?
Chemical nitrogen 1 it is pure as it does not have any inert gases. 2 it is lighter compared to atmospheric nitrogen. 3 it is highly reactive. Atmospheric nitrogen 1 it has 1% inert gases. 2 it is heavier than chemical nitrogen due to the dust particles. 3 it is less reactive because of the inert gases.
What are the two names for group 18 elements?
Elements of Group 18 may be called as;1-Noble gases 2-Rare gases 3- Inert gases
What is the highest inert gas?
Although there are many common gases that inert under most common conditions, the only ones that are inert under nearly all conditions are the noble gases. As an example - nitrogen is usually inert, but when subject to the conditions in an internal combustion engine, it will react to form a range of nitrogen-oxides.The noble gases - helium, neon, argon, krypton, xenon, and radon - are extremely non-reactive. Until the 1960's it was thought to be impossible to get them to react with anything because their oxidation number is 0. In the past 50 years a few compounds have been formed under very specially crafted conditions using highly oxidizing atoms like fluorine, but most of them are not even very stable.With that said - the highest atomic number for an inert gas is that for radon - which has an atomic number of 86 and an average atomic weight of 222 amu.Ununoctium (proposed name Oganesson) - with an atomic number of 118 and standard atomic weight of 294 is in Group 18 with the noble gases, but is predicted to be a solid due to relativistic effects: most of its properties can only be predictedbecause only 3 and possibly 4 atoms of this highly radioactive man-made element have ever been synthesized.
What is the charge of a Xe ion?
1.what is the oxidation state in xenon in HXeO4- and ... xenon is +7. As= +3 ... Xe = +7. As = +3 ... Except when highly electropositive elements are involved

Names of all metals and their uses?
hydrogen-gas helium-inert gas lithium-atomic no.3
What are 3 examples of gases dissolved in liquids?
liquid;vapour and ice
What 3 elements on the periodic table had complete outer shells?
All the Noble/Inert gasses. However, Helium (He) has a complete outer shell of only TWO(2) electrons. The other noble gases all have a complete octet (outer) shall, of EIGHT(8) (Octet) electrons.
Examples of 3 states of matter?
Solids-Rocks,Wood,Plastics............... Liquids-Water Gases-CO2.O2..................................
What are 3 examples of Bose-Einstein condensation?
These examples are: rubidium-87, sodium-23, and lithium-7 as very low density gases at extremely low temperature.
What are the 4 properties of inert gases?
1. relatively nonreactive 2. little tendency to gain or lose electrons 3. high ionization energies and negligible electronegativities 4. have low boiling points
What are facts about the nobel gases?
1. They are inert; they do not react with anything. 2. They each have eight valence electrons on their outermost electron shell. 3. Only two have ever been bonded with anything, and that was under extreme, simulated conditions.
What is an inert substance?
The "inert" or "noble" gasses are called that because they do not participate in any chemical reactions. They are: Helium, neon, argon, krypton,. xenon, and radon. (Xenon has been known to form compounds with other elements, but only at exceptionally low temperatures.) They are in Column 18 of the WebElements periodic table.
