  Pulses of high voltage sent through tubes containing xenon gas (a monoatomic gas) produce short, intense white light.  These tubes, called xenon flash lamps, have been used in the film industry and also in scientific research. next element                                 […]

    Kryptonite is the fictitious compound that takes away Superman’s strength.  Does this fictitious element contain the element Krypton?  In any event, Krypton is a monoatomic gas used in flashlights. next element                                          previous element

Argon exists as a monoatomic gas.  If electric current is passed through argon gas, the gas gives off a blue glow.  This is how blue “neon” lights are made.  Argon gas is also used in flashlights.   next element                                   […]

Neon exists as a monoatomic gas.  If electric current is passed through neon gas, the gas gives off a red glow.  This is now neon lights are made. next element                                            previous element

    Helium was first discovered on the sun though an analysis of the solar spectrum. At normal temperatures and pressures, helium exists as a monoatomic gas. The density of helium gas (0.2 grams per liter) is less than that of air (1.2 grams per liter), and because of this a balloon filled with helium […]
