None are.
There are five halogens that range from astatine (the densest) to fluorine (the lightest).
We do not know what Astatine smells like as it is radioactive and decays quickly into other elements. Therefore large quantities do not exist on earth. However, if it is like the others it will have a toxic and biting smell.
Iodine has a rather objectionable smell, especially as a vapour, but even the solid ( a dark, almost black crystalline solid at room temperature) has a slight pungent smell.
Bromine is a blood-red liquid at room temperature and has a pungent, harsh, biting smell that attacks the nasal passages.
Chlorine is a green gas at room temperature, and has a strong, harsh, biting, bleach-like smell. Again it attacks the respiratory system.
Fluorine is a pale yellowish gas which iis the most reactive of the halogens. It has a severely harsh bitinng smell that immediately causes severe pain due to the instantaneous destruction of the respiratory tract lining.
Therefore all the halogens are extremely toxic in the elemental state and have bad smells that vary depending on the haogen itself.

Does protactinium react with water?
Protactinium is a reactive metal; protactinium react with water vapours, acids, oxygen, halogens,etc.
Is iodine solution volatile?
it is very --------- Ions of halogens (including I-) are known as corrosive in solution; also hot iodine and vapours of some salts (ex.: CsI) are corrosive.
Why is acid rain colourless?
Are acids colourless? Yes they are. So acid rain is colourless
Why the brown color of bromine disappear when mixed with cyclohexene?
Halogens react with alkenes to form haloalkanes. Addition of the bromine in this case occurs across the double bond in cyclohexene. The resultant products are colourless hence the brown colour disappears.
Does ethene change from orange to colourless when it reacts with bromine water?
The ethene doesnt change from orange to colourless as ethene is already colourless but the bromine water turns from orange to colourless.
What is the name of the colourless substance when we burn fuels?
Carbon dioxide and water vapours
Does protactinium react with water?
Protactinium is a reactive metal; protactinium react with water vapours, acids, oxygen, halogens,etc.
What are physical properties of Xenon HexaFluoride?
At room temperature, xenon hexafluoride is a colourless solid. It will sublime into vivid yellow vapours.
What molecule is xenon hexafluoride?
XeF6 or xenon hexafluoride is a covalent molecule. At room temperature, it is a colourless solid that easily sublimes into intensely yellow vapours.
What are vapours?
water vapours are particles of water when water is boiled at a certain temperature the smoke you get is water vapours
Is iodine solution volatile?
it is very --------- Ions of halogens (including I-) are known as corrosive in solution; also hot iodine and vapours of some salts (ex.: CsI) are corrosive.
How is colourless in German?
colourless is farbloss
Are water vapours in air charged?
water vapours changed to clouds.from vivekganandan
Why is acid rain colourless?
Are acids colourless? Yes they are. So acid rain is colourless
What is the difference between water and water vapours?
water is a liquid but water vapours is steam... when we boil water it will turn into steam which is called water vapours...
