At room temperature fluorine is a faintly yellow gas with an irritating odour.
At room temperature and pressure pure fluorine is a very pale greenish yellow pungent corrosive gas.
At room temperature fluorine is a gas of diatomic molecules pale yellow when pure sometimes described as yellow green.
As fluorine is topmost in it s group these london forces are weaker and hence it has lower value of boiling point which is achievable at room temperature 25 degrees thus at room temperature fluorine and chlorine is gas bromine is liquid and iodine is solid astatine is radioactive and does not exist normally 1 5k views view 1 upvoter.
