1. Helium and neon are inert gases.

2. Inert gases such as helium have zero valencies. they do not normally form compounds.

3. A good choice is one of the inert gases; neon, argon, krypton, or xenon.

4. This indicates that the inert gases were acquired by a different means from carbon and nitrogen.

5. The inert gases are so called because they do not readily form chemical compounds.

6. He experimented on inert gases.

7. Behavior: These elements were considered to be inert gases until the 1960s[sentencedict.com], because their oxidation number of zero prevents the noble gases from forming compounds readily.

8. It'should be considered that inert gases will prevent the growth of aerobic microorganisms.

9. Two principal hazards exist in dealing with inert gases: asphyxiation and pressure.

10. Inert gases form clathrate hydrates when dissolved in water, astrict the activity of water molecule, prolong the store of fruits and vegetables.

11. The cold simulate of inert gases shrouding system of molten stream is studied in laboratory.

12. Isolate any leaking cylinders of inert gases in a well - ventilated area.

13. Inert gases generally to lubricant, hydrogen, nitrogen without effect can be used and compression dry air compressor oil to the same.

14. We educe a probability of the electric quadrupole emission of a photon induced by collision between two neutral atoms of inert gases.

15. ITO films with low sheet resistance can be obtained by raising the substrate temperature during deposition or annealing in the inert gases at high temperature.
