The main idea here is that these substances act as oxidizing agents. They readily accept electrons from other materials, which promotes the oxidation of fuels and can intensify fires. Fluorine and chlorine are gases at room temperature, and bromine can produce hazardous vapors that still behave as strong oxidizers. They themselves do not burn as fuels, but they can cause other materials to oxidize rapidly, which is why they’re categorized as oxidizing gases. They aren’t peroxides, which are a different type of oxygen-containing compounds, and they aren’t pyrophoric materials, which ignite spontaneously in air.
