What is the state of matter at room temperature of helium?
Helium is a colorless, odorless, tasteless and non-toxic gas at room temperature. It exists as a monatomic noble gas and is therefore inert and unreactive. It belongs to group 0 of the Periodic Table of Elements.
What is the abbreviation for gas helium?
The abbreviation for gas helium is He.
Does helium make gas?
Helium is a gas.
Is helium gas or plasma?

Gas. Helium is a gas.
Is helium a example of gas?
Yes. Helium is a gas
What is helium coloured gas?
Helium is a colourless gas
What gases are heavier than helium?
Helium exists as a monatomic gas, with atomic mass of 4.0. Thus any gas with a molecular mass higher than 4.0 would be heavier than helium. Hydrogen is the only gas that is lighter than helium; all others are heavier than helium.
Is helium gas a homogeneous mixture or heterogeneous mixture?
Neither. Helium is not a mixture at all, it is a pure substance.
Is helium gas a homogeneous mixture or a heterogeneous mixture?
Neither. Helium is not a mixture at all, it is a pure substance.
Which gas doesn't react at all?
Helium, Neon and Argon
What is true about atoms in helium gas?
They are helium atoms and have all the properties of helium. Helium is mono-atomic [as are all of the noble gases] Non-noble gases [those gases that react with other elements/compounds] are diatomic meaning that in the gaseous state the atoms are paired on to another.
