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.
What else can I help you with?
Does protactinium react with water?
Protactinium is a highly reactive metal and it can react with water, particularly in its radioactive forms. This reaction can release hydrogen gas and produce protactinium hydroxide. However, protactinium is rare and not often encountered in everyday situations.
Does ethene change from orange to colourless when it reacts with bromine water?
Yes, ethene reacts with bromine water to form a colourless solution. In the presence of ethene, the orange-brown color of bromine water disappears as bromine is consumed in the addition reaction with ethene to form a colourless compound.
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.
Are halogens the basis for all fossil fuels?
No, halogens are not the basis for all fossil fuels. Fossil fuels primarily consist of hydrocarbons, which are compounds made of hydrogen and carbon. Halogens, such as chlorine, fluorine, bromine, and iodine, do not play a significant role in the formation of fossil fuels.
Why are the halogens not found naturally in the earth's crust as the pure elements?
The halogens are not found naturally in the earth's crust as pure elements because of their extreme reactivity. Because the halogens are close to having completely filled electron shells, they will often react with other substances in order to gain an electron. As an especially noteworthy case, fluorine is the most reactive of the halogens (and elements in general), and will even react with glass. Therefore, the halogens are found naturally as compounds, not pure elements.
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 highly reactive metal and it can react with water, particularly in its radioactive forms. This reaction can release hydrogen gas and produce protactinium hydroxide. However, protactinium is rare and not often encountered in everyday situations.
What are vapours?
water vapours are particles of water when water is boiled at a certain temperature the smoke you get is water vapours
How is colourless in German?
colourless is farbloss
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...
Is helium a gas colourless?
yes. it is colourless
What color is zinc nitrate gas?
Colourless, or slightly white
Is oxgen colourless?
Oxygen is a gas, therefore it is colourless.
Elements in Group 17 are all called?
Halogens Apex ;)
Which halogen sublimes to violet vapours?
iodine is the only halogen in solid form. so it is the halogen which gives violet vapours on sublimation...
What is the noun of colourless?
The noun form for the adjective colorless (colourless) is colorlessness (colourlessness).
What are halogens and where are they located?
Halogens are in Group 7
