Helium is chemically inert as it has completely filled valence orbitals and it doesn't form any compounds.
There is no word equation, except that helium will exist as liquid phase in liquid helium
Yes. Mostly Hydrogen & Helium.
Argon Flourohydride and HydroHelium ion (+1) (HArF and HHe+ respectively).
there are no states of matter in helium.helium is a gas,wich is a state of matter.
Inert gases exist in the atmosphere; helium exist also in metane and some rocks.
The reaction in the sun which gives us energy involves helium. If helium didn't exist we would receive no energy and life wouldn't exist on the earth.
Helium has completely filled orbitals, is stable and is not reactive. Hence they exist as mono atomic
Helium does not combine with other elements and pure helium will exist by itself as elemental helium.
There is no word equation, except that helium will exist as liquid phase in liquid helium
helium cannot exist as solid and thus has no melting point
Helium does not exist in atmosphere as it is a very light gas.
Oxygen Fluoride which does not exist, but oxygen difluoride does exist. However, it is very reactive. It is a very strong oxidizer.
Yes, lithium fluoride is a compound. It is made up of lithium ions (Li+) and fluoride ions (F-), which are combined in a fixed ratio to form a stable chemical structure.
There are no known compounds of helium. Helium is a noble gas , it has a full valence shell with 2 electrons, (1s2).
Yes, helium can exist in a liquid state at very low temperatures, specifically below -268.9 degrees Celsius.
It would be CuF3 but this compound does not exist. Copper(II) fluoride, CuF2 exists, and K3CuF6 exists and contains copper III.
Examples are: ethane, hydrogen fluoride, hydrogen sulfide, chlorine, argon, nitrogen, oxygen, helium, etc.
