No, helium is a gas at room temperature.
what is the density of helium at room temperature?
helium is a gas
Helium is a gas at room temperature.
Helium is a gas because its density at room temperature under one atmosphere of pressure is so low that the atoms do not form a liquid or solid.
helium is a gas
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.
Helium is a gas at room temperature.
Helium is a colorless, odorless gas at room temperature and pressure. It is the second lightest element on the periodic table and exists as individual atoms. In the gas phase, helium atoms move independently of each other, making it difficult to define a specific shape for helium.
