Answer
Physical properties: pale-yellow, gas, melting point of -219.6 °C, boils at -188.1 °C.
Chemical properties: corrosive gas that reacts with practically all substances. Finely divided metals, glass, ceramics, carbon, and even water burn in fluorine with a bright flame. Small amounts of compounds of this element in drinking water and toothpaste prevent dental cavities
