WebHelium is symbolized by He and its atomic number is 2. Its boiling point and its melting points are the lowest compared to all the elements. Helium-3 and helium-4 are the only two stable isotopes of Helium. It is a colourless, odourless, tasteless, inert gas with very low density and viscosity. Helium is so light that it can escape Earth’s ... Helium (from Greek: ἥλιος, romanized: helios, lit. 'sun') is a chemical element with the symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas and the first in the noble gas group in the periodic table. Its boiling point is the lowest among all the elements, and it does not have a melting point at standard pressure. It is the second lightest and second most abundant element in the observable universe, after hydrogen. It is present at about 24% of t… pork apples and onions

WebA lifting gas or lighter-than-air gas is a gas that has a density lower than normal atmospheric gases and rises above them as a result. It is required for aerostats to create buoyancy, particularly in lighter-than-air aircraft, which include free balloons, moored balloons, and airships.Only certain lighter than air gases are suitable as lifting gases.
