WebHelium can’t be diatomic as two helium atoms never form a chemical bond for which it has to increase its orbit from ‘K’ to ‘L’ which is not possible for the fixed position of helium in … WebCrystals can be grown under moderate conditions from all 92 naturally occurring elements except helium, and helium can be crystallized at low temperatures by using 25 atmospheres of pressure. Binary crystals are composed of two elements. ... When cooled to low temperature, they form solids of diatomic molecules. Nitrogen has the hcp structure ...
WebFor a monoatomic ideal gas, the adiabatic constant is 5/3, and for a diatomic gas (such as nitrogen and oxygen) adiabatic constant is 7/5. For molecules with three atoms, it is 4/3. With an adiabatic constant 5/3 and molecular mass 4 g/mol for helium, the sound speed at 20C is 1007 m/s. That's why the voice in helium sounds so funny. WebSep 3, 2024 · In a monatomic (mono-: one) gas, since it only has one molecule, the ways for it have energy will be less than a diatomic gas (di-: two) since a diatomic gas has more ways to have energy (Hence, diatomic gas has a …
