Greetings, well, mention argon and neon, but especially "hydrogen argon" (H-35), due to its ability to develop a lot of energy by the excitation of ions to produce a high temperature, also as a luminous filler gas up to point of producing argon laser, in the case of neon it produces a reddish orange light, it is also used to manufacture high voltage indicators, this can also be obtained in liquid form in the form of cryogenic refrigerants. Oxygen also has the behavior of plasma, used in fusion energy by applying two stimulus discharges to two electrodes.
