Gases that are lighter than air include water vapor, methane, hot air, hydrogen, neon, nitrogen, ammonia and helium. These gases have a lower density than air, which causes them to rise and float in the atmosphere. Many lighter-than-air gases provide lifting power for airborne objects.

Helium (He, atomic number 2) is an extremely light, inert gas at room temperature and pressure.The liquid form of the element is the only liquid known to man that cannot be solidified, no matter how low the temperature drops. Helium is so light it can escape the atmosphere and bleed away into space.; Neon (Ne, atomic number 10) consists of a mix of three stable isotopes.

The second lightest element on the periodic table is Helium (He). The easiest way to tell this is by the numbers on the periodic table, all elements are in atomic weight order (super-light gases ...

en.wikipedia.org/wiki/Inert_gas

An inert gas is a gas which does not undergo chemical reactions under a set of given conditions. The noble gases often do not react with many substances, and were historically referred to as the inert gases. Inert gases are used generally to avoid unwanted chemical reactions degrading a sample.

There are a few types of gases that can be found in a light bulb. Usually only one type of gas is found in a single bulb. The first type of gas used, and one found in common incandescent bulbs, is argon. Sometimes the argon gas is mixed with nitrogen. Some light bulbs contain halogen or xenon gas. Krypton gas is also found in some light bulbs.
