Helium is chemically inert as it has completely filled valence orbitals and it doesn't form any compounds.
no
There is no word equation, except that helium will exist as liquid phase in liquid helium
Above -268.93 °C, helium is gas. Below -268.93 °C, helium is liquid. Helium cannot exist as solid.
neon and helium
Yes. Mostly Hydrogen & Helium.
yes. it does exist
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.
no
Helium does not combine with other elements and pure helium will exist by itself as elemental helium.
Helium has completely filled orbitals, is stable and is not reactive. Hence they exist as mono atomic
There is no word equation, except that helium will exist as liquid phase in liquid helium
Helium does not exist in atmosphere as it is a very light gas.
helium cannot exist as solid and thus has no melting point
Above -268.93 °C, helium is gas. Below -268.93 °C, helium is liquid. Helium cannot exist as solid.
neon and helium
Oxygen Fluoride which does not exist, but oxygen difluoride does exist. However, it is very reactive. It is a very strong oxidizer.
There are no known compounds of helium. Helium is a noble gas , it has a full valence shell with 2 electrons, (1s2).
