The noble gases include helium, neon, argon, krypton, xenon, and radon. 1  Helium has the atomic number two and is the second most abundant element in the universe. 2  Neon has the atomic number ten and is commonly used in lamps for the red-orange glow it gives off when exposed to electricity.  Argon has the atomic number 18.
The only chemical elements which are stable single atom molecules at standard temperature and pressure (STP), are the noble gases. These are helium, neon, argon, krypton, xenon and radon. The heavier noble gases can form chemical compounds, but the lighter ones are non-reactive or inert. For example, helium, being the simplest noble gas, has only two electrons, thus meaning it is satisfied with a complete outer shell, making it relatively non-reactive, hence it is a noble gas.
