helium has completely filled valence orbitals similar to that of noble gases and is chemically inert at room temperature.
Helium in a chemical element, and an inert gas. It does not want to be an electrical conductor, so it is considered an insulator.
Yes, helium gas is considered a pure substance because it is made up of only helium atoms. It is a unique element with its own distinct chemical properties and characteristics.
Helium is considered an inert noble gas. Only some unstable compunds of helium are known today: HeNe, HgHe10, WHe2.
Helium is considered the most unreactive gas because it is a noble gas with a full outer electron shell, making it very stable and unlikely to react with other elements.
The abbreviation for gas helium is He.
No gas is considered an ice unless it is solid. All gases (except helium) can be solidified by cooling, by pressure or a mixture of both.
No. Helium is an inert gas, therefore, it is not conductive.
Helium is considered a stale gas because there isn't a new source of it being added at any given time. An example of a non-stale gas would be oxygen, which is constantly renewed.
Helium is a gas.

Gas. Helium is a gas.
Helium is an inert or noble gas, and it remains a gas at anything but the lowest temperatures. It is a member of Group 18 of the periodic table, and helium is not considered a metal.
