Do not say fluorine gas, it is the strongest element, do not say that electronic anti-matter and current, authority ah
Chlorofluorinated Chloride C1F5 Chlorinated Fluorinated Chloride is a non-combustible, non-combustible colorless gas with strong irritating odor at room temperature. Its solid state is white and has a pale yellow color. It is rapidly hydrolyzed to form chlorine and hydrofluoric acid It is a strong oxidizing agent that reacts strongly with most of the inorganic matter, so that although it does not burn in the air, it can cause fire and explosion.
Oxygen is a colorless, almost odorless highly toxic gas, liquefied after the pale yellow. Because of the oxygen at room temperature with the dry air can react quickly to produce nitrogen dioxide and moldy colorless Gas nitrogen trifluoride (fluorine gas at room temperature with the dry air almost no reaction, which can be seen in the oxidation of tungsten fluoride), so usually see the fluoride is a brown odor of brown gas.
